I booked a cheap mileage redemption from SEA to IND with a connection in PHX. First leg is on AS and second leg is on AA. When booking, I neglected to double-check the terminal situation at PHX, and now I realize that I will have to leave security at T3 and take the train to T4 to catch the AA flight. I currently have 2.5 hours. No checked bag or anything like that, any reason why I should abandon this flight and go through ORD or somewhere like that instead?

Thanks.
