Earnings Call: Q3 2019

Jan 23, 2019

Operator

Good evening, ladies and gentlemen, and welcome to IndiGo's conference call to discuss the third quarter fiscal year 2019 financial results. My name is Stanford, and I will be your coordinator. At this time, the participants are in listen-only mode. A question and answer session will follow today's management discussion. As a reminder, today's conference call is being recorded. I would now like to turn the call over to your moderator, Mr. Ankur Goel, Associate Vice President of Treasury and Investor Relations for IndiGo. Thank you, and over to you, sir.

Ankur Goel
Associate VP of Treasury and Investor Relations, IndiGo

Good evening, everyone, and thank you for joining us for the third quarter fiscal year 2019 earnings call. We have with us our Co-founder and Interim Chief Executive Officer, Rahul Bhatia, and our Chief Financial Officer, Rohit Philip, to take you through our performance for the quarter. Ronojoy Dutta, our Principal Consultant, Wolfgang Prock-Schauer, our Chief Operating Officer, and Willy Boulter, our Chief Commercial Officer, are also with us and available for the question and answer session. Before we begin, please note that today's discussion may contain certain statements on our business or financials which may be construed as forward-looking. Our actual results may be materially different from these forward-looking statements. The information provided on this call is as of today's date, and we undertake no obligation to update the information subsequently. A transcript of today's call will also be archived on our website.

We will upload the transcript of today's prepared remarks within an hour. The transcript of the question and answer session will be uploaded subsequently. With this, let me hand over the call to Rahul Bhatia.

Rahul Bhatia
Co-Founder and Interim CEO, IndiGo

Good evening, everyone, and thank you for joining us on this call. We announced our third quarter fiscal 2019 financial results today. This quarter, we reported a profit after tax of INR 1.9 billion with a profit margin of 2.4%. Though we have seen a reduction in fuel prices during the quarter compared to the previous quarter, on a year-over-year basis, fuel prices are still 31% higher and the Indian rupee is weaker by 11%. Both these factors have impacted our profitability compared to the same period last year. Our unit revenue was down year-over-year, but we saw an improvement in revenue performance during the quarter. It was encouraging to see a year-on-year improvement in RASK in November and December on account of improvement of the fares in the zero to 15-day window. Rohit will talk about this when he takes you through our financial performance in detail.

As we have said before, we are focused on building a large and profitable air transportation network in and out of India and are adding capacity in line with our long-term growth plan. We added a net of 19 aircraft this quarter and ended the quarter with a total fleet of 208 aircraft. This has enabled us to expand our network both domestically and internationally. Talking about our domestic operations first, we have increased our daily domestic departures by 75 flights per day during the quarter. While some of the metro airports are getting slot constrained, we are encouraged with the growth that we are seeing in tier 2 and tier 3 cities. In addition to our focus on our domestic network, we have also strengthened our international presence. We started operations from six new international destinations and added 22 international routes during the quarter.

As part of our international expansion strategy, we have entered into our first codeshare and mutual cooperation agreement with Turkish Airlines. This will allow IndiGo customers to reach several European destinations beyond Istanbul. Our unit costs, excluding the impact of fuel and foreign exchange, declined on a year-on-year basis. As we add more A320neos and A321neos in our fleet, we expect further unit cost improvements. Maintaining our cost leadership is fundamental to our business, and I am happy that we remain firmly on track to reduce our unit costs further. We also remain focused on our operational performance. We were ranked as one of the best airlines for the second consecutive year amongst the top 20 mega airlines globally in terms of on-time performance based on the data compiled by OAG. IndiGo is the only Indian airline to have made it to this list.

During the quarter, we had an on-time performance of 79.1%, technical dispatch reliability of 99.87%, and a flight cancellation rate of 0.45%. Now let me take a step back and recap the year that has gone by. Going into the year, we set ourselves very ambitious growth targets to tap into this very unique opportunity that the Indian market presents. Over the last one year, we have taken delivery of 55 aircraft, roughly one aircraft a week. Not many aviation companies globally have the resilience and the organizational strength to grow this rapidly and still continue delivering strong operational performance. We have delivered on all parameters, be it ensuring adequate availability of pilots and cabin crew, growing the network to new markets, strengthening the internal processes, and improving efficiencies. I would like to thank all our employees, especially the operational staff, for their tremendous performance.

In past, we have focused on setting up the right network domestically. Now with this in place, we are looking to strengthen our international presence. We have received our first A320neo, which has a higher seating capacity and lower unit costs compared to the A320neos, and also has long range. We plan to start direct flights to Istanbul from March and open other international destinations as the year progresses. Overall, I'm happy with the way we have grown so far and remain very excited with what lies ahead. With this, let me hand over the call to Rohit for a detailed overview of our financials. Thank you.

Rohit Philip
CFO, IndiGo

Thank you, Rahul, and good evening, everyone. For the quarter ended December 2018, we reported a profit after tax of INR 1.9 billion compared to a profit after tax of INR 7.6 billion during the same period last year. We reported an EBITDAR of INR 16.8 billion with an EBITDAR margin of 21.2%, compared to an EBITDAR of INR 20 billion with an EBITDAR margin of 32.4% during the same period last year. As Rahul mentioned, our profitability was lower compared to last year, mainly on account of the increase in fuel price and the depreciation of the Indian Rupee. The average aviation fuel price in India during the quarter was 31% higher than the same period last year. After adjusting for the increased volumes, this increase in fuel price resulted in higher fuel costs of INR 7.3 billion compared to the same period last year.

The Indian Rupee closed at INR 69.71 per US dollar. The average exchange rate for the quarter was INR 72.1 compared to INR 64.8 in the same quarter last year. This had an adverse year-over-year impact of INR 2.7 billion on our dollar-denominated expenses. Our total capacity for the December quarter was 21.6 billion ASKs, an increase of 32.9% compared to the same period last year. Our revenue from operations in the December quarter was INR 79.2 billion, an increase of 28% over the same period last year. Our other income was INR 3.1 billion for the quarter. Our RASK for the quarter was INR 3.70 compared to INR 3.82 during the same quarter last year, a decline of 3%. While in October, our RASK showed a similar decline as it has in previous months, we saw a much better RASK performance in November and December.

This improvement in our RASK performance was largely because of improvement in yields, especially in the 0 to 15-day booking window during these months. For the quarter, our yields were up by 3.7% to INR 3.83, while our load factors were down by 3.2 points at 85.3%. Our CASK for the quarter was INR 3.61 compared to INR 3.16 during the same period last year, an increase of 14.5%. This increase was primarily driven by an increase in fuel prices and currency depreciation. The currency depreciation also impacted our CASK excluding fuel, and as a result, our CASK excluding fuel was INR 2.04 in the current quarter, an increase of 6.3% from the same period last year. Excluding the impact of foreign exchange, our CASK excluding fuel reduced by 0.4%.

We remain relentlessly focused on maintaining our cost advantage and have taken steps to create efficiencies and further improve productivity across the organization. Our balance sheet continues to be strong. Our cash balance at the end of the period was INR 141.4 billion, comprised of INR 46.2 billion of free cash and INR 95.2 billion of restricted cash. Before I close my remarks, let me give you our capacity guidance for the coming quarter. We expect a year-over-year capacity increase in terms of ASKs of 34% for the fourth quarter. With this, let me hand it back to Ankur.

Ankur Goel
Associate VP of Treasury and Investor Relations, IndiGo

Thank you, Rahul and Rohit. To answer as many questions as possible, I would like to request that each participant limit themselves to one question and one brief follow-up if needed. With that, we are ready for the Q&A.

Operator

Thank you very much, sir. Ladies and gentlemen, we will now begin the question and answer session. Anyone who wishes to ask a question may please press star then one on their touchtone telephone. If you wish to remove yourself from the question queue, you may press star then two. Participants are requested to use handsets while asking a question. Ladies and gentlemen, we will wait for a moment while the question queue assembles. To ask a question, please press star then one. The first question is from the line of Ansuman Deb from ICICI Securities. Please go ahead.

Ansuman Deb
Research Analyst, ICICI Securities

Hi. Thanks for the opportunity. Regarding the good improvement in RASK that we have seen. This quarter, did we have any P&W compensation? If not, then could you give a brief color on the delta that we saw between October and November, December? If we see sequential fares have increased by almost 23%. There's a very strong pattern that we have seen in November, December. Some color on that would be useful.

Rohit Philip
CFO, IndiGo

Yeah, sure. Let me answer the first question on credits. There's no year-over-year improvement on account of credits, it's all related to passenger revenue. I'll let Willy comment on the trend in the quarter.

Willy Boulter
Chief Commercial Officer, IndiGo

Sure. As Rohit pointed out, October was another month in which the pricing in the market was very competitive.

As we ran into Diwali and into the peak season in November and December, the pricing environment improved quite markedly. The key improvement was in that 0 to 15-day booking period, where as opposed to the previous quarter we reported on and there was a very large reduction in yields. In this quarter, the yields, looking at the year-on-year picture, stayed stable. As a result, the RASK number was a lot better. I hope that that gives you the sufficient color.

Ansuman Deb
Research Analyst, ICICI Securities

Yeah, thank you. One last question was regarding our search for the CEO. Any update on that? Because post the retirement of Gregory Taylor, do we have any update on that?

Rohit Philip
CFO, IndiGo

We hope to have an update fairly soon.

Ansuman Deb
Research Analyst, ICICI Securities

Okay. Thank you

Rohit Philip
CFO, IndiGo

we're working on it. Thank you.

Operator

Thank you. The next question is from the line of Ronil Dalal from Ambit Capital. Please go ahead.

Ronil Dalal
Research Analyst, Ambit Capital

Yeah, hi. My question was, ancillary revenue has grown by around 15%. What would you say is the breakup of this ancillary revenue? Second is, interest and depreciation costs are much higher on a year-on-year basis. Any reason for the same? Usually, you used to give capacity guidance of the coming year and maybe one or two quarters. This time it's only one quarter. Anything on that? Thanks.

Rohit Philip
CFO, IndiGo

Let me answer a few things and then turn it over to Willy. The interest and depreciation was primarily due to two factors. We've taken a number of ATRs that we've acquired through cash purchases, as we've talked about in the prior quarter. The asset base has increased. One component is that, and the second component is related to the owned aircraft on our balance sheet, over the last year have gone through several engine shop visits where those engine shop visits are capitalized and has increased the depreciation. Those are the two components that has increased the run rate of depreciation this year, which you'll see, and there's also a currency impact on that as well. That's depreciation. On interest, the currency impact is the issue.

In terms of capacity guidance, we normally give capacity guidance for the fiscal year in the last quarter of the year. We'll give you guidance for the next fiscal year on the next quarter's call. We'll update you then. In terms of ancillary, I'll just comment on the breakup of ancillary is about 30% cargo and 70% passenger. The weakness in why it's not grown in line with capacity is mainly on the cargo side, and maybe, Willy, you want to comment anything on?

Willy Boulter
Chief Commercial Officer, IndiGo

There's a few things to say about ancillaries. I think we, in this call six months ago, indicated that we were going to be putting more emphasis on selling ancillaries. Apart from the cargo side, there are a number of categories of ancillary. Obviously, there are cancellation charges, there's advertising, there's onboard sales, there's various products to help the passenger's journey through the airport, et cetera. It's gratifying that we are getting some improvement in that ancillary revenue. I would say, though, that we are very mindful that by global standards, we are still below what would be an average for a low-cost carrier, and we continue to focus on that. Turning to cargo, it's a wider issue. We are delighted that we've managed to improve our market share. It was about 24% in April.

It's now in the sort of 27%, 28% region. We, again, as indicated, I think, on this call six months ago, we again are putting a lot of effort behind cargo, and we hope that that share will move closer to our passenger share.

Ronil Dalal
Research Analyst, Ambit Capital

Thank you. Sure. Hello?

Rohit Philip
CFO, IndiGo

Yep. Please go ahead.

Ronil Dalal
Research Analyst, Ambit Capital

Yeah. One last thing is that the dollar-denominated deposits, we had mentioned that last time it was around one-third of the supplementary lease rentals. Any update on the same?

Rohit Philip
CFO, IndiGo

Yes, we've continued to increase the number of dollar-denominated leases. Now about 80% of our supplementary rent liability is collateralized with dollar deposits. The exposure to the rupee on the mark to market on this, it used to be in the order of INR 1 is equal to INR 85 crore. Currently it's from INR 1 is equal to INR 24 crore. By the end of next quarter, I think we'll pretty much be fully hedged.

Ronil Dalal
Research Analyst, Ambit Capital

Sure. Okay. Thank you. All the best.

Rohit Philip
CFO, IndiGo

Thank you.

Operator

The next question is from the line of Achal Kumar from HSBC. Please go ahead.

Achal Kumar
Analyst, HSBC

Hi. I've got a few questions. One about the capacity growth. As Rahul mentioned, a lot of capacity is coming on the tier 2 and tier 3 cities. According to the OAG data, you're getting significant capacity growth on the new routes. For example, Kannur. These days, a lot of news about Kannur. You're starting a lot of new flights. How do you see this will impact the yield? It looks quite dangerous. A lot of capacity is coming in the new routes. That is one thing. Secondly, I want to understand about the recent news on your stalled. You had a plan to start Europe, but now the news says that you have stalled the plan. Previously, Mr. Rakesh Gangwal talked a lot about this, saying that these operations are good. Now what has changed?

Is there any change in the strategic directions? What has changed? Last thing I want to understand about the November-December. You said the 0 to 15 days window, the fare has strengthened. Is there any change in your strategic approach from RASM, looking at the load factor to now, are you concentrating more on the yields? Thanks.

Ronojoy Dutta
Principal Consultant, IndiGo

Okay. This is Ronojoy Dutta, and I'll take the question on the international first. We are going to grow international very aggressively. Our international growth for this year, coming quarter, for example, 30% of the growth will be international. To the specific question of have we given up on going to Europe or to London? The answer is no. It's very much alive, and we are looking at it, and we'll take a decision soon. At this point, it's neither a yes nor a no. Your other question was what's happening in the second-tier markets? Really, it's quite encouraging that although we are growing so rapidly, that we don't see a negative impact on our unit revenue. Most other companies, like Southwest or easyJet, when they talk about their earnings, they say, "Here's what's happening to our new markets, which are developing markets.

There we've taken a unit revenue hit. On the rest of the market, we're doing fine." We don't see any such distinction. It's quite encouraging to see all these new cities that we are going into. They've responded so well. We don't see any sort of weakness in RASM as a result of new markets. Was there a fourth question there?

Rohit Philip
CFO, IndiGo

About the load factor and yield.

Which I'm happy to talk about. I think as we discussed last time, the RASK is a balance of load factor and yield. It's a competition that never goes away in a sense, as one looks forward and looks at forecasting and so on. Revenue management is about a mix of load factor and yield, and that's the way it will be. I think some of our competitors concentrate perhaps rather too much on the load factor part of it, but I'll leave it at that for now.

Achal Kumar
Analyst, HSBC

Okay. Mr. Dutta, you talked about the European and U.S. market, I'm sure European market is slightly different. In terms of India, when we talk about India, you know that in India market, when we talk about the new sector and new routes, the gestation period is, I think, much longer than what it is there in Europe. Don't you think that will have a sort of impact on the yield, and probably you'll have to wait for the longer term to sort of increase the fares? That is one thing. Now especially when everybody is growing in the next year, in 2019, if you see that Vistara is growing. Leaving Jet Airways apart, GoAir is growing, SpiceJet is growing. If everybody is growing, don't you think that could actually raise the competition?

Ronojoy Dutta
Principal Consultant, IndiGo

Okay. When you said that European and U.S. markets are different, it's true that in Europe and U.S., typically, they talk of a six-month gestation period. What was surprising looking at the Indian market is that there is no such thing domestically as a gestation period of six months. We've grown a lot of new flights, as you can see from our schedule. They're all doing surprisingly well. I don't see that as an issue at all.

Rohit Philip
CFO, IndiGo

Achal, if we can request you to go back into the queue and give others a chance to ask questions, we'd appreciate it.

Sure.

Thanks.

Ronojoy Dutta
Principal Consultant, IndiGo

Okay.

Operator

Thank you. The next question is from the line of Ashish Shah from Goldman Sachs. Please go ahead.

Ashish Shah
Analyst, Goldman Sachs

Thank you, sir, for the opportunity. As I look through your data, what we see is that we have added two ATRs this quarter, but our own/finance lease has not gone up; it is remain 29. Are we now also doing operating lease on ATRs?

Rohit Philip
CFO, IndiGo

Yes, Ashish. We have done two operating leases on ATRs. On the last two ATRs. We have taken the first 12 ATRs as cash purchases. I think as I've mentioned on prior calls, during the periods of uncertainty, it's always prudent for airlines to manage cash carefully. We decided to finance the next tranche of five airplanes through operating lease. Then we'll make a case-by-case basis beyond that. These two, as well as the next three ATRs, we're going to take on operating lease.

Ashish Shah
Analyst, Goldman Sachs

Okay. There's no change in strategy. This is just a temporary measure where just to preserve the cash we are taking it on a operating lease.

Rohit Philip
CFO, IndiGo

That is correct.

Ashish Shah
Analyst, Goldman Sachs

Okay. Sir, if you could give some more color on the yields there. Do you think these yields are sustainable, and how do you see the environment going forward?

Rohit Philip
CFO, IndiGo

I think all I'd say on this for the time being is that the better environment that we had in November and December has continued so far. We see that there is some discipline in imposing advance purchase requirements. That, I think as we described again last time, is the critical issue when we look at the development of yield in the Indian market.

Ashish Shah
Analyst, Goldman Sachs

Okay. Thanks a lot. Thank you.

Operator

Thank you. The next question is from the line of Rohan Gupta from Edelweiss. Please go ahead.

Rohan Gupta
Research Analyst, Edelweiss

Yeah. Hi, sir. Congrats on a great set of numbers.

Operator

Excuse me. This is the operator. Mr. Gupta, may we request you to use the handset, please? Your voice is not clearly audible.

Rohan Gupta
Research Analyst, Edelweiss

Hello. Yeah, can you hear me?

Operator

Yes. Please go ahead, Rohan.

Rohan Gupta
Research Analyst, Edelweiss

Yeah. Congrats on a great set of numbers. I had a couple of questions. Firstly, on yields. Given the slowdown which we have seen over the past couple of months, where growth has slowed down to around 12% for the industry and a number of players are expanding capacity at around 30%, do you think that yields would be sustainable at these levels? Is it possible that we may see a cutback in capacity in the future in order to maintain yields? Secondly, on the significant increase in cash balance. We have seen a net cash accretion of around INR 1,300 crores versus a cash profit of roughly INR 400 crores. Presumably, there is a decrease in working capital. Can you please elaborate on this breakup as well? Yeah.

Rohit Philip
CFO, IndiGo

If I can talk about the capacity issue. By and large, when a country is growing at an X GDP, I'm sure you're all familiar with the notion that air traffic growth, that it is twice that rate.

Rohan Gupta
Research Analyst, Edelweiss

Yes.

Rohit Philip
CFO, IndiGo

Right now the industry is growing at about 19%. If the underlying economy is growing at close to eight, 7.7, I think is the exact number, it would say, yeah, the industry should grow at that rate. Our specific capacity, if you look at last year and this year in two years in unison, we've been a little lumpy in the sense that in 2018, we didn't grow enough. Our domestic capacity grew by only 10%, while Spice was at 21%, Go was at 27%, Jet was at 11%. We grew slower than everyone else. Now this year, we're playing catch up. Yes, we are growing faster. But even then, our domestic capacity is growing at only 25%. The industry is growing at 19%. These would all be major issues if the underlying economy was not growing.

When you have a close to 8% growth in the economy, you would say, yeah, the industry should be growing at least double that rate. I don't see that as much of an issue. Again, I would stress the fact that our future capacity, a lot of it is going to go international. Overall, yeah, we are quite happy with the capacity decisions.

Rohan Gupta
Research Analyst, Edelweiss

For 2019, can we expect capacity growth at 30% for domestic, or would it significantly slow down?

Rohit Philip
CFO, IndiGo

I think we'll come and we'll give you a more precise guidance with the next quarter. What we've said previously is we expect about 25% a year over the last three years. It might be a little bit higher than that, but we'll give you a more precise guidance next time. Should I maybe turn to your question on cash? The cash balance increased on the restricted cash and on the free cash side. On the free cash side, it was about INR 250 crore increase, and the rest was in restricted cash. Yes, obviously, the increase was bigger than the profits. We do get some incentives when we take delivery of aircraft and that helps with the cash balance. Some of that gets deposited in restricted cash to securitize these obligations. Net-net, that's what drives the increase in cash balance.

Rohan Gupta
Research Analyst, Edelweiss

That lease incentive, does it also show up in other income, or is it entirely on the balance sheet?

Rohit Philip
CFO, IndiGo

I think you can follow up with Ankur to understand this in more detail, Our accounting policy basically has the lease incentive gets amortized over the life of the lease. On the P&L side, you recognize it over six years, while on a cash flow basis, you get it upfront. We can explain it to you in more detail offline if you'd like.

Rohan Gupta
Research Analyst, Edelweiss

Okay, got it. Okay, thanks a lot. Yeah, that's it.

Operator

Thank you. The next question is from the line of Rohan Advant from Multi-Act. Please go ahead.

Rohan Advant
Investor, Multi-Act

Yeah, thanks for the opportunity. My first question was on the growth in engine rentals, which is 46% on a year-over-year basis. That is much higher than the ASK growth and the depreciation of the currency. Do NEOs have higher rentals versus the CEOs, and that is why it's much higher?

Rohit Philip
CFO, IndiGo

I think obviously the currency depreciation plays a part in that. Then there are some credits that offset lease rentals that appeared last year as well as this year. When you net all that out, that's why you see the percentage is a little higher than the growth in capacity and the currency depreciation.

Rohan Advant
Investor, Multi-Act

Okay. The NEOs, would they have higher rentals than the CEOs?

Rohit Philip
CFO, IndiGo

On a net basis, there's differences in CEOs and NEOs, especially when you talk about older planes. You'll have lower lease rentals, especially the used planes that we have have lower lease rentals, but higher maintenance costs

Wolfgang Prock-Schauer
COO, IndiGo

Higher fuel burn. NEOs might have slightly higher rentals, but lower maintenance costs and lower fuel burn. You can't really compare it, unless you're comparing it apples to apples.

Rohan Advant
Investor, Multi-Act

Okay. Lastly, on the lease period for the new NEOs that we are getting, is that also for six years, or are we doing a higher lease period?

Wolfgang Prock-Schauer
COO, IndiGo

Currently, we're doing them on six-year sale lease backs.

Rohan Advant
Investor, Multi-Act

Okay. Thanks for taking my questions.

Wolfgang Prock-Schauer
COO, IndiGo

Okay.

Operator

Thank you. The next question is from the line of Chockalingam Narayanan from BNP Paribas Mutual Fund. Please go ahead.

Chockalingam Narayanan
Head of Research, BNP Paribas Mutual Fund

Yeah. Hi. Thanks for the opportunity. First is on the NEO engine issues. Where are we as far as what's the update from Pratt & Whitney? When can we see these issues kind of getting normalizing?

Wolfgang Prock-Schauer
COO, IndiGo

Yeah. Wolfgang here. As you know, initially we had certain issues with the NEO engine. Most of the technical issues have been resolved. Modification programs are in place or have been already modified or are in progress to be implemented within a short period of time. Just recently, one month ago, there was a meeting of the Indian regulator, DGCA, with the operators, in India on NEO aircraft. There was also a contact with FAA. FAA has confirmed that all the engines are well within the limits prescribed by this regulator and also by DGCA. Just to give you an example, the in-flight shutdown rate is, per FAA, the U.S. regulator, 0.05 per 1,000 engine flight hours. We operate at 0.02. We are well within the norms set out by FAA, and there's, as per FAA, no need for further measures to be implemented.

However, DGCA was asking us for some more regular checks, which we are doing anyhow. We did on our own. For us, the situation is completely under control. Nearly all but one aircraft is AOG right now. Otherwise, all aircraft are flying. We don't see any restrictions on the engine side for our further expansion going forward.

Chockalingam Narayanan
Head of Research, BNP Paribas Mutual Fund

Just on a few incidents in between in the media, I think smoke and other issues. Also about possibly the regulator asking us not to fly on the Andaman route. Basically, on large stage length, long stage length routes. In that sense, will it be a constraint as far as flying international on the NEO flights, both A320 and A321?

Wolfgang Prock-Schauer
COO, IndiGo

On this Port Blair, that's correct. Regulators asked us not to operate to Port Blair, that's not out of flight safety reasons. It's more of logistical reasons. If something happens to transport an engine there, for engine change, it's more complicated. That's why we are not flying to Port Blair. With respect to international expansion, we don't see any restrictions because most of our routes we want to expand are normal operations, you have to have a diversion airport within 60 minutes of your flight path. We don't see any restriction on that side. On top of that, we have about 40 CEO aircraft, which are ETOPS aircraft that we use mostly from South India to the Gulf, where you will fly a larger proportion of your journey over water.

Combined with these 40 ETOPS means extended range operations, with our A320s, A321 NEOs, which will fly the routes with the 60 minutes diversion airport, we don't see any restrictions coming up in our expansion.

Chockalingam Narayanan
Head of Research, BNP Paribas Mutual Fund

Thanks. That's very useful. Secondly, on capacity constraints at the key airports, what's the thought process and how do you see your ability to grow market share out of these key routes?

Wolfgang Prock-Schauer
COO, IndiGo

Actually the A321 is a universal aircraft which can be used for longer flights. It can fly up to six hours or more than six hours and will also be used into capacity constrained airports. For example, you have destinations where you have 15, 16 frequencies a day. If you use a couple of A321s on these rotations, you can free up slots, you can expand to other destinations. It's for us a very useful universal aircraft which we can use for international expansion and also domestic expansion in capacity-constrained airports. Bringing our seat mile cost down because of the larger capacity. We are very happy to have the aircraft coming in.

Chockalingam Narayanan
Head of Research, BNP Paribas Mutual Fund

How much would the fuel burn increase if you deploy this on shorter stage lengths? Say like a Delhi-Mumbai, if you operate, will the fuel burn actually increase if you deploy A321 on this?

Wolfgang Prock-Schauer
COO, IndiGo

It all comes down to the cost of operating a seat. Definitely with this kind of aircraft, you will have something like 10% lower seat mile cost approximately. Our cost of bringing one seat from, let's say, Delhi to Mumbai will be 10% lower.

Ronojoy Dutta
Principal Consultant, IndiGo

Just as a reference point, we asked Airbus that where are people using them on short-haul, high-frequency routes? As I recall from memory, they gave us the numbers for both Air France and Lufthansa, who have a lot of A321s. The average stage length was for less than two hours of flying.

They are used on short-haul, high-frequency routes all over the world. Your point was that you won't have enough slots in Delhi and Bombay. Well, having 222 seats per aircraft is a huge advantage in those markets.

Chockalingam Narayanan
Head of Research, BNP Paribas Mutual Fund

That's very useful. That was just to better understand that aspect on the fuel burns. Thanks a lot and very good set of numbers. Thank you.

Ronojoy Dutta
Principal Consultant, IndiGo

Thank you.

Thank you. The next question is from the line of Kunal Lakhan from Axis Capital. Please go ahead.

Kunal Lakhan
Analyst, Axis Capital

Yeah. Hi, good evening. Just to follow up on the previous question. How should we look at the fleet mix going ahead with the infusion of A321 now? Going ahead, like incrementally the number of fleets that we'll add, how should we look at the mix in terms of I understand there is 150 plane order of A321. Just over the next couple of years, if you can give some color on how the fleet addition via A321 will be, that would be helpful.

Rohit Philip
CFO, IndiGo

Yeah. As you know, we have an aircraft order of 450 NEOs, out of which we have the ability to, with adequate notice, ask Airbus to deliver any one of the A320 family, which includes A319, A320, A321s. We don't intend to take any A319s at this point, but we will take a number of A321s going forward. We expect to take actually a large number of next year's deliveries with A321s, then we'll continue to assess that and make those decisions on an ongoing basis. The mix will definitely increase upwards in terms of increasing the mix of A321s.

Kunal Lakhan
Analyst, Axis Capital

Yeah. Just another follow-up on that would be that the deployment strategy for these fleets would be on the trunk routes, right? I mean, you'll not look at deploying these on the sort of non-trunk routes.

Ronojoy Dutta
Principal Consultant, IndiGo

That is roughly correct, yeah. A321s, their first primary mission will tend to be international. Then to some extent, they'll be domestic. You're right, we'll obviously put them into high-demand, slot-constrained routes, which takes you into the trunk routes. Yes.

Kunal Lakhan
Analyst, Axis Capital

Thank you. That's helpful. Secondly, on the yields front, you mentioned that November, December saw some improvement in the 0- to 15-day window. How are we seeing that in January so far? Maybe also for the quarter, if you can share.

Rohit Philip
CFO, IndiGo

In January. Well, I think as I mentioned earlier, the trends that we saw in November and December continue within the market, and we're obviously content with that.

Kunal Lakhan
Analyst, Axis Capital

All right. Thanks a lot, and all the best.

Operator

Thank you. The next question is from the line of Joseph George from IIFL. Please go ahead.

Joseph George
Analyst, IIFL

Hi, this is Joseph from IIFL. My first question is in relation to the comment on yields. Now there's a lot of excitement in the investor community today because of the 20 odd % QOQ jump in yields. What I want to check is how much of this is seasonality, because obviously 3Q is seasonally far stronger than 2Q, and how much of it is actually an underlying improvement in demand? That's the first part of the question. Second part is when you talk about Jan being as good as November and December, are you implying that the high yields that is prevalent in the seasonally strong November and December period has continued into Jan? Are you saying that on a year-on-year basis, the improvement that you saw in November and December, that same rate of year-on-year improvement has continued into Jan?

Rohit Philip
CFO, IndiGo

I think that, yes, we are saying that there is still some improvement. I mean, I'm sort of straying into commercially sensitive areas here, so I don't want to say too much on this. Rohit, let me just set some context here. Firstly, I think on a quarter-on-quarter basis, it's always very difficult to explain the numbers because of the seasonality. That's why we look at it on a year-on-year basis. On a year-on-year basis, I think as we talked about, yields were up for 3.7% for the quarter. That included a yield decline in October, with yield improvements in November and December on a year-on-year basis. Compared to a seasonally strong quarter a year ago, we saw improvements in November and December yields. Again, on January, year-on-year, January is again getting into a slower quarter.

We are talking about it all on a year-on-year basis. That's usually the comp. Willy, you want to add anything?

Ronojoy Dutta
Principal Consultant, IndiGo

No, I think that's fine. As I say, I mean, traditionally, we don't really comment on performance going forward too much.

Rohit Philip
CFO, IndiGo

Yeah. I think that's what we tried to add the color of what we've seen so far in January, those trends. Which is really driven by the fact that the fares in the zero to 15-day window remain strong, and that's what we had not seen the last couple of quarters.

Ronojoy Dutta
Principal Consultant, IndiGo

If I were to make a macro-level statement, I would describe our situation as follows. We are growing rapidly. We are growing into new markets. Despite all that, our unit revenue picture is firm. Which I think is a surprising situation to be in, frankly. That's how I would describe our overall situation.

Joseph George
Analyst, IIFL

Got that. Thank you. The second question that I had was, you mentioned that you have moved about 80% of the deposits corresponding to the restricted cash into USD deposits. Would it be right for me to assume that the investment income that we are, this is purely for the purpose of modeling, investment income that we are modeling in future periods, the yield on the overall cash balance should come down? I mean, it's quite logical, but just want to confirm.

Rohit Philip
CFO, IndiGo

Yes.

Joseph George
Analyst, IIFL

Got it. The last question that I had was, while you talked about the improvement in the 0 to 15-day window, what we have also noticed is that there's a fall in load factors. To some extent, it can be said that the improvement in yield, the 3.7%, 3.8% year-over-year improvement in yield, has come at the cost of volumes. If that is the case, how do you really measure the improvement in underlying pricing if the yields just come at the cost of volumes?

Wolfgang Prock-Schauer
COO, IndiGo

Well, I could say that part of the reduction in load factor is because of our very fast growth. Growing at 30%, it's certainly a tall order to keep the same load factor the previous year. Having said that, I think that the yield picture is a relatively bright one, and I don't have any particular concerns, as I say, moving forward.

Rohit Philip
CFO, IndiGo

I think just to again address your question more directly, you are talking about against 3.7% improvement in yield for the full quarter and a 3.2% decline in load factors roughly offsets each other. For the quarter, our RASK performance was roughly flat. It included this sort of phenomenon of October, which was very negative, and an improvement in November and December. In November and December, the improvement in yield is much more significant than the loss in load factor. It's definitely the right trade-off from our perspective.

Joseph George
Analyst, IIFL

Perfect. Got it. Thank you.

Operator

Thank you. The next question is from the line of Sanjay Doshi from Reliance Mutual Fund. Please go ahead.

Sanjay Doshi
Senior Analyst, Reliance Mutual Fund

Good evening, sir, and thanks for the opportunity. Sir, I just wanted your comments on the overseas strategy. You mentioned earlier in the call that the growth in terms of capacity addition will be much higher in the overseas business. Obviously the three, two, ones will provide you a greater opportunity to service a larger market. I just want your thoughts about the kind of competition and the behavior of those competition in the international market, and how does that business stack up versus your key domestic routes and the tier 2, tier 3 cities in terms of profitability?

Ronojoy Dutta
Principal Consultant, IndiGo

We have a huge advantage in going international in that we are going with single-aisle planes. That also restricts us to within 6 hours of flying. You can draw a map around all our principal cities and say, "Where are these guys going to fly? Where are we going to fly in that 6-hour radius, if you will, from each of the principal cities?" When we are flying in those, we have a single aisle at a low cost. We are clearly not trying to get the business class traffic, which we don't have a business class. In those markets that we are going to fly with a single-aisle, low-cost strategy, we have a huge cost advantage. We are very excited about our growth opportunities internationally. Just to give you another metrics, if you will.

Right now, we carry 6% of the international traffic in and out of India. Foreign carriers carry 61%. We have a huge opportunity for growth. When we say, "Oh, we are growing rapidly," yeah, we've not grown internationally at all for decades. Now we're just trying to claw back which we believe is rightfully ours. We are very excited about international. We have the right airplane, we have the right cost structure, we think we'll make strong headway internationally.

Wolfgang Prock-Schauer
COO, IndiGo

If I may add here. We are the only carrier having a huge domestic network behind our international expansion. We can connect something like 40 to 50 domestic destinations to our international market, which gives us a unique advantage over the other foreign carriers, also smaller Indian carriers. We want to connect the huge domestic network with a very fast-growing international network, we have also started certain preparations in that context, reducing minimum connecting times to make a hassle-free journey from the hinterland of India into our international destinations.

Sanjay Doshi
Senior Analyst, Reliance Mutual Fund

Understood, sir. Sir, just on that second part of the question, how is the competition behaving differently, if at all, in your international business today, what is there in the domestic? In terms of profitability, if you can just rank the three key businesses that we can segregate. Overseas, domestic key routes, and the tier 2, tier 3 domestic.

Ronojoy Dutta
Principal Consultant, IndiGo

Okay. I think it's phases of growth, right? Our first phase, and as you'd logically expect, would be in the metro to metro. We've grown that. The market is mature. We'll grow it somewhat slowly. As you said, we go from A320 to A321. We have more seats for departure. We'll continue that focus. What has been exciting is the tier 2 cities. Didn't expect that much growth and that much response to our added capacity. After Hyderabad, we do the 6 metros. You have a range of cities. I've just mentioned places like Ahmedabad, Pune, Nagpur, Lucknow, Guwahati. These are all tier 2 cities which are like, wow, I didn't realize there was so much traffic in those cities. That's great. The third area of growth now will be international. How will the competition behave?

Well, all these hubs, they rely on their feed from other places. If you do city to city strategy, clearly they would win. As Wolfgang said, they had their feed into, I'll pick Singapore or Dubai or any of these places. They have the feed at the other end. Now for the first time, we have feed into our major gateway cities. We have Indian feed into Delhi and Mumbai and Chennai and all of these cities. Yeah, we can fight off Singapore and Dubai quite forcefully, I believe, with our feed. I think your overall question was where do you see it growing? Well, we saw the first phase over with the trunk routes. The second phase is in play right now, the second tier 2 cities, and they're responding very well. Now the third phase will be international expansion.

Sanjay Doshi

Thank you. The next question is from the line of Pulkit Singhal from Motilal Oswal Asset Management. Please go ahead.

Pulkit Singhal
Analyst, Motilal Oswal Asset Management

Hi, thanks for taking my question. When I look at the last five years, your ASK growth has largely been in the 18%-20% range, barring FY 2017, where it was 27%, and which incorporated one odd quarter of 30% kind of growth. In each of those years, your load factors had gone up, which to me is demand outstripping supply at that price point. This year and going ahead, your ASK growth is at a higher trajectory and you are much larger in the market share in the market. This is the first time I've seen that load factors are coming down. Is it to say that the demand growth may be slower than the kind of capacity addition that you're doing at the price point right now? Because this is quite different from what we've seen in the previous five years.

Ronojoy Dutta
Principal Consultant, IndiGo

Let's take a longer-term perspective. This is all predicated on the fact that the Indian economy remains strong. If it doesn't, we have a different problem. There's nothing that says the Indian economy won't continue to be one of the fastest-growing economies in the world. The second factor that comes into play is what they call the propensity to travel. Given the GDP, what should we expect? Well, developed countries are 10 times higher than us in terms of the propensity to travel. You have two factors working for you. Let's say a 7.5% growth rate and a low propensity to travel, which gets higher and higher as people have more income. With both of those combined, there's no reason to expect that aviation traffic shouldn't grow at between 18%-22%. I'm now including international and domestic.

Yes, domestic, we've got a good share. Internationally, we have a minuscule share. As I said, 6% of the international is what we share right now. Why can't we grow that to 25%? I'm just picking a number. If we have domestic capacity, our market share is 43%. If you want to grow to 25% of the international traffic, just imagine the number of airplanes we need. We need a lot more planes, frankly. What's happening also is we're getting new technology planes, which is why we're growing so fast, because the new technology planes are lower unit cost. Our older planes will tend to mature and go out of the system, and therefore we need more planes. Yeah, if anything, there's a desire to buy more planes, grow faster, because we see lots of opportunities all around us.

Pulkit Singhal
Analyst, Motilal Oswal Asset Management

Right. Basically, you're saying that the domestic market can absorb 18%-20% increase in capacity, the rest will flow into the international, that's why your growth rate is higher between 25%-30%.

Ronojoy Dutta
Principal Consultant, IndiGo

Absolutely. Even this year, 70% of the growth has gone domestic, 30% growing international. You'll continue to see that as we go forward.

Pulkit Singhal
Analyst, Motilal Oswal Asset Management

Do you think the 18%-20% growth in domestic will require fare stimulation? I'm taking out the competition aspects completely, in your view, does that require fare stimulation or it can be at flattish rates as well?

Ronojoy Dutta
Principal Consultant, IndiGo

We are looking at revenue growth of 18%. Now, it can come in load factors, it can come in yields, this twice, two and a half times the GDP growth is looking at revenue. Airlines can choose to take it in any mix they think is appropriate.

Pulkit Singhal
Analyst, Motilal Oswal Asset Management

Got it. Thank you, all the best.

Ronojoy Dutta
Principal Consultant, IndiGo

Again, I think you should look at China and what happened to their aviation traffic as they grew. It was breathtakingly fast and sustained for a long period of time. I think we are just entering that phase.

Pulkit Singhal
Analyst, Motilal Oswal Asset Management

No, I completely agree. We have around 3.75 billion. The propensity to travel is already there when we just see the number of rail tickets sold in the country. It is just that, as you are getting into the newer tier 2, tier 3 cities, hopefully that will help get a lot of those people on board.

Ronojoy Dutta
Principal Consultant, IndiGo

Yeah. I beg to differ in that the propensity to travel in India is still among the lowest in the world.

Pulkit Singhal
Analyst, Motilal Oswal Asset Management

Got it.

Ronojoy Dutta
Principal Consultant, IndiGo

We are far behind Brazil or any other developing market and way behind Europe or the U.S.

Pulkit Singhal
Analyst, Motilal Oswal Asset Management

Okay. From an air travel perspective, I presume you're referring to?

Ronojoy Dutta
Principal Consultant, IndiGo

Sorry, what? Air travel.

Pulkit Singhal
Analyst, Motilal Oswal Asset Management

I presume you're referring to air travel. I was referring to overall travel in the country.

Ronojoy Dutta
Principal Consultant, IndiGo

Absolutely.

Pulkit Singhal

Okay. Got it. Thank you, and all the best.

Ronojoy Dutta

Thank you. The next question is from the line of Ansuman Deb from ICICI Securities. Please go ahead.

Ansuman Deb
Research Analyst, ICICI Securities

Yeah. Thanks for the opportunity again. I had one question regarding the perspective that some of the competition as well as government point of view that we already have a domestic market share of 43%. I understand that we are doing a lot of international and there we can have a lot of unbridled growth. Just to put a number in domestic market share, is there any regulation or is there any limit to which IndiGo can grow after which there would be some kind of a government intervention or some rules which can play out, especially in the domestic market?

Rahul Bhatia
Co-Founder and Interim CEO, IndiGo

Well, this is Rahul. To the best of our understanding, there is no limit. I think IndiGo is always very cautious about sort of its market share and consequently, we try to behave very responsibly. We don't want ever to be seen as an airline, which is either gouging the customer or the competition. We're just trying to be an efficient company, trying to connect the country from all corners, and we'll continue to do so.

Ronojoy Dutta
Principal Consultant, IndiGo

Really, I think IndiGo should be given a lot of credit and appreciation for the kind of infrastructure building that we are doing. The government is putting a lot of emphasis on building roads, which is great. They want to build river traffic. They want to build ports. They want to revamp the railways. Thank God they don't have to worry about the airline side of it. We are taking care of building great infrastructure. We are not only doing it in an elitist sort of way that only a few people can travel, we are doing it for the affordable fares for the mass. You look at how we've connected Guwahati to Chennai and Jaipur to Amritsar and all these cities, and it's the fantastic infrastructure that we've built, which is great for the nation.

I don't know why anyone would object to this and say, "No, no, you're growing too fast." We're growing too fast. We're building great infrastructure for the country. Which sort of builds on the economic prosperity of 7.5% growth that we're talking about. Without this sort of air traffic infrastructure, that growth would slow down. I don't see why the government should be concerned. Most importantly, we are doing it in a self-sustaining way. Everyone wants to build the infrastructure, they can't think of a way of doing it profitably. We are demonstrating that we can.

Ansuman Deb
Research Analyst, ICICI Securities

Great. That's very helpful. One last question was regarding to Mr. CFO, if we can add some more color on the accounting of credits that we are doing right now in terms of compensation from P&W and whether we can expect some more time between compensation in the coming quarter. In the sense that I want to understand that because of some groundings, we would have expected some compensations already, but it has not been there. If any possible, I know you don't share the quantum of the same, but in case you can give some color on the accounting and the trend of that.

Rohit Philip
CFO, IndiGo

Yeah, sure. Obviously, it's something that is competitively sensitive and contractually sort of confidential, and that's why we're unable to give the specific details, as you can appreciate. Directionally, I think we've talked about this before. We do get some credits from the manufacturers to offset the effect of aircraft groundings and delivery delays. Some of those credits are offsetting sort of lost revenue or higher expenses that get recorded in the revenue line or the expense line as appropriate. If you looked at last year, in the similar period, we had a larger number of aircraft groundings, and so the quantum of that compensation you can imagine was higher than it was in this current quarter. That's pretty much the color that we've shared previously, and that's what we can share right now.

Ansuman Deb
Research Analyst, ICICI Securities

Okay. Thank you.
