A220 market is hugeProblem is AB/BBD can’t build them fast enough to show the airlines that they can support future backlog and deliver on time. This is one of the reason Mobile FAL was build to show airlines that they can build faster in the future. This will be AB’s sales pitch. What does BA/EMB going to show to meet makert demand. Also A220 suffered from development delays and then engine delays and now interior delay (mainly seats). Most of this problem are gone and are slowly going away during this slow ramp up. Problem is that AB, Bomber, BA and EMB are all ramping up and most of their tier 1 and 2 suppliers are common with their competitors. Ramp up for supplier are the bottle neck. Again this is slowly getting cleared as suppliers ramp up. It’s matter of time when A220 operations gets humming along. A220 will have a huge order from AA, UA, and Air France. Maybe BA as well but it looks doubtful until Brexit issue settles down. I am not sure but AB can go after BA/EMB for dumping if E2’s are sold well below list price as A220 out of Mobile is now domestic product while E2 are not.
