I've always been interested in LAX's place in UA's route system. In what way is it a hub? I can understand it being something of a TPAC gateway and also a gateway to Mexico, but does it serve in any way as a banked domestic hub?
It's also very interesting as a hub since it has massive O&D traffic and so it doesn't have to be a great *hub* in order to be profitable.
Also, regarding AA "building up" at LAX: What does that mean WRT their PHX hub?
