I think that AA has a reasonably compelling proposition to the business market:
widespread inseat power
widespread (getting there) inflight internet
best frequent flyer program

When things pick up again, they may be in the best position to take advantage of that.

I think an E+ style seating arrangement might be a helpful feature (call it legs AND laptop) but I don't know if the revenue premium is enough to justify the lost seats given the load factor.

My company's preferred airlines include AA, UA and WN. But I have to say "I'm leaving in this time frame, and need to arrive at X in this timeframe" and the travel coordinator has a 3 hour window to work with around that to get the lowest fare. So it would be hard for AA to command a premium over UA or WN in that situation.
I think my company's style of travel policy is going to become more common compared to "Book J on whoever" that may have been in the past.

AA is engaged in a game of chicken with the other legacies, waiting to see who'll go away first. There is a general opinion (not necessarily correct) that once one of the legacies goes away the rest can raise fares easily and everything will be fine with them. AA may be doubling down and betting that if they go bankrupt they can Ch11 because they never have before and that none of the other airlines would be able to again.
