Boeing (NYSE: BA) and TUI Group, the world's number one tourism business, today announced its selection of 18 737 MAX 10s at the 2017 Paris Air Show. TUI Group already had 70 unfilled orders for the 737 MAX and will convert 18 of these existing orders to the 737 MAX 10. The leisure group is the first European operator to select the latest member of the 737 MAX family of airplanes.

"Being the first to fly the new larger 737 MAX 10 in Europe means we'll be able to take more customers on holiday in the most advanced, most comfortable and most fuel efficient aircraft," said David Burling, Member of the Executive Board and responsible for TUI Group Airlines. "The continued modernization of our fleet and the delivery of the new 737 MAX, now including the 737 MAX 10, will support the delivery of TUI's commitment to reducing the carbon intensity of our operations."

TUI Group aims to operate Europe's most carbon efficient airlines and has committed to reduce the carbon intensity of its operations by a further 10 percent by 2020.

The 737 MAX 10 is the largest member of the 737 airplane family, the world's best-selling jetliner family.

The MAX 10 will be the most profitable single-aisle airplane, offering the lowest seat-mile cost ever in a commercial aircraft. The 737 MAX 10 has more range than today's Next-Generation 737s and substantial fuel efficiency and economic advantages over heavier competing models, including five percent lower trip cost and five percent lower seat-mile cost.

"The 737 MAX 10 will provide TUI with the lowest seat costs of any single-aisle airplane in operation today," said Ihssane Mounir, senior vice president of Global Sales & Marketing, Boeing Commercial Airplanes. "We are honored that TUI Group is the first European customer to select the 737 MAX 10 and are confident it will play an integral part in its continued success."

Like Boeing's other 737 MAX models, the MAX 10 incorporates the latest technology CFM International LEAP-1B engines, Advanced Technology winglets, Boeing Sky Interior, large flight deck displays, and other improvements to deliver the highest efficiency, reliability and passenger comfort in the single-aisle market.

Along with the 737 MAX, TUI Group has unfilled orders for four 787-9 Dreamliners. The Group also has 50 options for the 737 MAX and has converted 10 of these to the 737 MAX 10. The Group will take delivery of its first 737 MAX aircraft in January 2018.
