OTOH, those who have 737s on order really don't have any options. Airbus single aisles are sold out for the rest of the decade and Airbus probably can't significantly ramp production since all of its many suppliers would have to go along with that, which spells Airbus entering into contractual obligations it is probably rightly reluctant to make.
Still, Boeing needs to get its act together pronto.
This latest debacle that can only be laid at the door of Boeing will ensure to further delay the type certification of the Max 7 and 10 as well as the 777X.
After all of the water that's passed under the bridge, what regulatory authority would trust Boeing?
