Southwest is feeling the heat now. In a lot of ways, I find what the airlines are doing more interesting than whatever gongshow is going on within Boeing - mostly since its only a mass defection/cancellation event is honestly the most likely path (in my mind anyways) Boeing has to getting the type of culture fix it apparently needs now.
EDIT: I am aware of how long Airbuses order queue is (its like 8-10 years deep at this rate). I know why this makes a mass defection unlikely. And this same logic is why I think Boeing can't possibly have the conditions for a proper culture change in time without an actual mass defection soon. A myopic management and board at Boeing can look at the current situation, see the depth of the Airbus queue, and conclude that they have a short term crisis to manage. And as long as no one defects (or they hit their next problem) that's true. And short term crisis is no reason to actually change strategy.
