thanks all. it was all on AA. i saw the fare through kayak. perhaps i'll go straight to aa.com and check to make sure. they wouldn't sell the ticket on one itinerary unless it was kosher, right?

also, cbn42, i did check the flights after, and there are 3 after the one i'm supposed to be on including one 30 minutes later. so i think i'll go ahead with that booking.

appreciate everyone's help.
