look on aa.com for the gate occasionaly to see what the flight is using if you want an idea....however, they change, often close to flight time....

i always check the gate before going to the a/p...usually it holds, but i have had 3 or so changes before it left....

i wouldn't make tight time plans based on a terminal assumption.....

i plan to get to the remote parking lot 1:45 or so before flight time...check the gate/terminal again before getting on the bus...

good luck..
