I’m not trying to defend Boeing and I also think the problem for 737max is a serious blow to boeing, but I suspect the only chance for massive cancellations of its orders is when ffa designates it as a new airworthiness type. Even that might depend on contract details. What also make the cancellations less likely, in my opinion is that its competitors, the A320neo has a backlog of more than 10 years at the current production rate. And the smaller a220, the former bombardier cseries, has a backlog of almost 400 planes. Besides, at 2019 France air show, IAG put an order of 200 737max in a letter of intent which is quite surprising and strange
