Even when the CEO controls the money side of the equation? Good luck with that, especially when there's a large difference in contracts.
So back to the original question. Who's in play.
Delta? I don't think they would get past the DOJ on the size.
AA/US? The same, especially since they aren't close to completing theirs.
UA/CAL? A mix of both of the above.
HAL? Not sure that works too well together with two very specific regions.
Pretty much leaves Southwest.
What are the other ideas out there?
How do you figure DL, AA/US, or UA/CAL + AS would be too large...but not AS+SWA???
Alaska does not dominate any market...even in SEA, we don't dominate to the same level that Delta dominates ATL, AA dominates DFW or US dominates CLT.
Alaska wants to be independent, so AS isn't going to go out and buy anybody. They have their "growth" plan locked in for the next decade, assuring the current managements job-security for the forseable future so that requires somebody to buy AS.
HA, Republic, Mesa, Skywest, forget it - AS would be too big a prey.
SWA - If there is any DOJ justification to intervene, I think it lies with SWA. That being said, I think SWA is not going to be interested in acquiring anyone for a very long time.
AA/US - The west coast is the backwater of the US as far as AA is concerned and I think they are perfectly happy sub-contracting the flying out to AS.
JBLU - I think it would be a great match up if it were a merger but I don't think JBLU is big enough to do it without the cooperation of AS management.
UAL/CAL - I think this is a very good possibility since they don't have anything to lose. In the 90's, everybody was sure that the big merger was going to be NWA/CAL for the same reasons that the popular prediction is DAL/AS today.
DAL/AS - I think it's still the most likely for reasons that have already been discussed.
