TUI Travel has committed to 60 Boeing 737 Max aircraft in a deal valued at $6.9 billion at list prices.
These aircraft includes 40 of the 737-8 variant and 20 -9 variant. It also has the option to purchase another 90 737 Max, although the deal is still subject to shareholders' approval, says the travel operator.
The 60 aircraft, scheduled to be delivered from January 2018 through to March 2023, will be powered by CFM International Leap-1B engines.
UK-based TUI Travel owns and operates six European airlines - Thomson Airways, TUIfly, TUIfly Nordic, ArkeFly, Jetairfly and Corsair. Altogether, they operate 141 aircraft.
