oh because you're not an AA cheerleader right ??That's an easy one. Mergers may have been good for DAL and UAL because neither of them merged with LCC. NW had its very valuable Asian franchise and CO had its huge lock on Houston and Newark (which some people refer to as NYC despite its location in New Jersey). On top of that, NW had a strong domestic network in MSP and DTW plus some good European traffic. CO had a pretty decent presence in Asia as well as its European and domestic networks. LCC brings PHL, CLT and PHX along with some European fights. AA isn't struggling because it lacks hubs in PHL, CLT and PHX, despite what the LCC-cheerleaders say.
