So I have recently purchased a RT ticket from IND-SEA on AA. When I go to AA's My Trip, and 'Select' the trip, I was taken to US Airways' page. The flights are listed as operated by AA. Now when I go to 'View/Change Seats' on the US Airways' trip page, I was told to return to AA to change my seat. So it seems like I'm stuck in an infinite loop of rebounding between the two sites. Anyone has a similar experience? Is there a way out of this (other than calling AA to get seat assigned)?
