great stuff - i would love to see usair expand their international presence here in charlotte. however i dont see us (charlotte) as having the one way traffice to get us to south america. 90 percent of the passengers would be connecting meaning the routes would probably be unsustainable.
also, AA has flights to south america (santiago, buenos aires, quito, lima, guayaquil, rio, sao paulo, all through colombia, etc. . . in fact, aa has the best route coverage in south america of any us airline.
with a united merger, i think we would lose charlotte hub to dulles due to proximity. continental would be okay from a route standpoint.
kinda exciting the potential growth from charlotte!!!! (now if we could only get those direct fares down)
