Boeing has announced the launch of the 737 MAX 10 as the newest member of the 737 MAX family at the 2017 Paris Air Show.

The 737 MAX 10 will have the lowest seat-mile cost of any single-aisle airplane ever produced. 

The airplane has gained wide market acceptance with more than 240 orders and commitments secured from more than 10 customers worldwide.

Customers will be announcing order details throughout the week.

“The 737 MAX 10 extends the competitive advantage of the 737 MAX family and we’re honoured that so many customers across the world have embraced the outstanding value it will bring to their fleets,” said Boeing Commercial Airplanes president, Kevin McAllister.

“Airlines wanted a larger, better option in the large single-aisle segment with the operating advantages of the 737 MAX family.

“Adding the 737 MAX 10 gives our customers the most flexibility in the market, providing their fleets the range capability, fuel efficiency and unsurpassed reliability that the 737 MAX family is widely known for.”

The 737 MAX 10 continues the MAX family’s range advantage over competing models and will deliver five percent lower trip costs and five percent lower seat-mile costs.

Design changes for the 737 MAX 10 include a fuselage stretch of 66 inches compared to the 737 MAX 9 and levered main landing gear.

The airplane has the capacity to carry up to 230 passengers.

Other changes include a variable exit limit rating mid-exit door, a lighter flat aft pressure bulkhead and a modified wing for low speed drag reduction.

The 737 MAX continues to be the fastest-selling airplane in Boeing history, accumulating more than 3,700 orders to date.
