I may be the only person here concerned about this particular implication. I don't think it warrants a new thread.
Am I correct that, for the time being, there will still be two separate liveries flying? I ask because I write and update travel guidebooks. The "How to Get Here" sections for several Latin American countries presently include both AA and US, at the level of detail, for example, that "American flies from Miami and Dallas; US Airways flies from Charlotte," and not beyond that. I remember having a grace period where I was still able to mention both UA and CO following that merger.
I realize there could be some eventual consolidation of hubs, and a given Latin American destination might not receive flights from MIA, DFW, and CLT. For the time being, though, things shouldn't change too drastically?
Gracias.
