US did try to scoop up Delta when they went Ch 11, so I'd expect them to try the same trick this time. I can't imagine AA management being keen on the idea and they will undoubtedly do what they can to stay independent.

If you fly mostly in North America, the idea of AA/US/WS all in the Oneworld alliance is intriguiging and would create real competition, but for those who do a lot of international travel, I can't imagine many of them dropping AC and its non-stops in order to one-stop with Oneworld.
