Actually, I'm hoping that the East pilots can dump ALPA before any potential merger takes place. At that point they get stapled and all hell breaks loose.They just didn't want to get involved with this trailer mess.
The big question is, if US is a player, is the west included?
What US does have going for it is that is still a pretty significant amount of capacity, mostly secondary, that is a prime candidate to be removed. Someone may be interested just to shut it down, although major mergers between the other four would probably have the same result.
