E,
your disagreement with the antitrust issue is incorrect because it is based on faulty logic.
1. There is no size limit in any anti-trust legislation that specifically says above which a merger cannot happen because the combined entity is too large.
2. There is no antitrust legislation that says that market share must be evenly divided between any number of competitors.
3. There is no antitrust legislation that says that a given number of competitors must exist in any market.
Practically,
sure from an antitrust perspective the notion would be that an AA/B6 merger would present less overall size that would create antitrust issues, but even an AA/B6 merger would leave the combined entity far larger at JFK than anyone else with the likely requirement that a certain amount of slots would have to be divested.
There is nothing that says a so-called low fare carrier is less exempt from anti-trust enforcement than any other carrier.
.
AS would be the best solution, but the whole notion of AA combining w/ someone else is predicated on the fact that AA would not be able to restructure on its own and another airline would have to absorb AA in order to provide a lifeline to ensure AA's survival. If AA can make it on its own, they will be looking for merger partners POST BK and in that case AA likely would be the surviving entity.
But until AA has fully emerged and has demonstrated that it can make it on its own to the satisfaction of its stockholders (current creditors), AA will be the one that will be THE ACQUIRED.
A smaller company is just not going to take on the acquisition of a larger company that uses a different business model.... the fastest way for AS or B6 to end up in BK itself and fail would be to take on a business model they don't know and one that quite frankly is not at all solid with AA.
.
Thus, a merger or asset acquisition involving AA this side of emergence will involve another network carrier - one that has the resources and the similarity of business models to ensure that they are not taken down by acquiring AA or even its most valuable parts, which is driven by their int'l operations.
