Boeing has launched the 737 Max 10 as the fourth major version of the re-engined single-aisle family with more than 240 firm orders and commitments from more than 10 customers.
"Today it is or pleasure to announce we are officially the launching the newest member of our 737 Max family – the 737 Max 10," said Boeing Commercial Airplanes chief executive Kevin McAllister at the Paris air show this morning.
The identities of the 737 Max 10 customers will be revealed in announcements scheduled throughout the show, McAllister says.
The 737 Max 10 is designed to seat up to 188 passengers in dual-class and 230 in single-class layouts.
As a 1.67m (5.5ft) stretch of the 737 Max 9, the new version becomes the longest version of the 50-year-old single-aisle type.
It will compete against the Airbus A321neo, which has outsold the 737 Max 9 by a five-to-one margin.
