As a Bay Area customer where AS has significantly pared back their offerings the last few years, I was hopeful that we'd see a deeper partnership between the two airlines. While it's great being able to earn AS miles on any AA flight, the lack of codeshares or AS marketing of AA flights hasn't made much of a difference in being able to seamlessly travel from my home airport without relying on a competitor alliance (or Southwest). I realize being in an alliance together isn't the same as a JV, so maybe these things just aren't possible, but this seemingly half-assing of things just doesn't go far enough to make a meaningful improvement. Would love to be able to buy an AS ticket that takes advantage of AA's flights out of my closest airport that lets me mix and match segments between the two airlines.
