I guess it all depends on what you consider huge. Delta and United are huge. American will shrink in BK and there is no guarantee after shedding all those super 80s if they will be able to take delivery of those new planes. Many jobs will be lost. I have been through this Bk process. If AA can emerge on its own great if not a Pan Am style break up will most likely happen. US is doing fine and will soon sign better contracts (they are just about done with negotiations)with higher pay and better work rules than American will have for years to come.AA is going to be a huge low cost carrier when it emerges from BK. AA does not need US to become larger than it is today. With A319s on the way , AA will be going back into many many lost markets. Dont forget the our big Oneworld partners BA/IB who will also be feeding AA's domestic network for additional revenue. I think UAL would be a better fit for US, not AA.
