I now declare that the polls are closed. While the Inspector of Election complete the vote tabulation, I will comment briefly on our business performance for 2018. 2018 demonstrated steady continued progress on a solid foundation.
We augmented our leadership team with skilled technology executives, evolved our go to market strategy and made strong progress on our technology evolution. Our commitment and execution to the strategy we laid out at the beginning of 2018 resulted in solid financial and operational performance. We delivered strong full year results well ahead of our original expectations coming into the year. Total revenue was 3,900,000,000 dollars an increase of 7%. Total adjusted operating income was $701,000,000 a decrease of 1%.
Full year adjusted earnings per share increased 10% to $1.54 per share. Finally, free cash flow totaled $41,000,000 an increase of 22%. Each of our business units contributed to the solid full year results and delivered commercial and operational progress consistent with our strategies. At Travel Network, we grew revenue 10%. Strong global share gains was driven by the completion of the Flight Centre migration, increased share gain at large with global travel management companies, including CWT and other new agency conversions.
The continued global rollout of our Sabre Red 360, our next generation agency desktop, produced improvements in agency productivity, conversions and commissions. We became NDC certified Level 3 as an aggregator and as an IT provider and kicked off our Beyond NDC partner program. Finally, we announced new lodging innovations in our partnership program with booking.com. At Airline Solutions, we grew revenue 1% with over 5% full year passengers boarded growth on a consistent carrier basis. Our progress is driving strong product health and customer relations led to a higher rate of renewals and new implementations in 2018, including the implementation of SabreSonic at LATAM Airlines.
We introduced and began to roll out the first phase of our Sabre commercial platform, the industry's first end to end intelligent retailing and fulfillment platform and the most significant advancement across SabreSonic and AirVision in over 5 years. At Hospitality Solutions, we grew revenue 6% with strong revenue in central reservation system transactions, driving double digit growth in recurring Sodexa software and services revenue. We signed new wins, key renewals and increased share of wallet at hoteliers around the world and announced the successful completion of the Wyndham Central Reservation System implementation. Finally, I would like to acknowledge my team members around the world with a sincere thank you. Their collective work and effort in 2018 were a major contributor to the progress we made.
Thanks so much for your participation today. I'll now turn the call over to Steve to report out on the voting results. Steve?
Thank you, Sean. First, let me say that these results I'm about to announce are preliminary. We'll file the final results with the SEC on a Form 8 ks within 4 business days. The Inspector of Election has advised me that each of the 4 nominees for director was elected for a 1 year term. The selection of Ernst and Young as the company's independent registered public accounting firm was ratified.
The company's 4th amended and restated certificate of incorporation was adopted. The company's 2019 Omnibus Incentive Compensation Plan was approved and the company's 2019 director equity compensation plan was approved. With that, I'll turn it over to Larry to adjourn the meeting.
Thank you, Steve. I'd also like to take

With that, the meeting is adjourned.
