Due to Air Jamaica no longer flying direct from O'Hare, we are flying on US Airways and connecting in Charlotte before arriving in Montego Bay on December 15th.
My question is: do we check-in at the international terminal (terminal 5 in O'Hare) or the domestic terminal (terminal 2 = US Airways)?
Since our 1st flight isn't technically an international flight, and there will be other passengers on our flight whose final destion will be Charlotte or another US city, I thought we'd just go to the regular Terminal 2 to check-in. However, I e-mailed my travel agent and she said to check in at the international terminal.

Hoping someone here has done something similar at O'Hare.
