March 7, 2017, © Leeham Co.: If Boeing builds the 737-10, which appears increasingly likely, will customers come?
This is always the multi-billion-dollar question for any aircraft and engine manufacturer.
For Boeing, launching the 737-10 is a low-risk, and in the eyes of many, futile effort to stem the bleeding of market share between the MAX 9 and its rival, the Airbus A321neo.
Depending on who’s counting and how the numbers are calculated, the A321 sales outpace the MAX 9 by a factor of four or five to one. LNC calculated last year that the ratio is more likely 3:1, identical to the market share split between the predecessor airplanes, the 737-900ER and the A321ceo.
