OK, I'm new to the AA Board (always been DL & US) but making the big leap to AA. Anyway, I'll be travelling with my 4 small kids (PHL-DFW-SLC), what exactly is involved with this "TERMINAL CHANGE"? And why the big ALERT warning like it is something terrible? I've changed terminals many times, [ATL, PHL, STL, CVG, LAS, SAN, PHX, etc.], other than MCO, I never found it to be more than a little longer walk. Are there shuttle busses involved, and time issues? Would anyone recommend routing through ORD to avoid this "terminal change". My connection times are an hour and thirty minutes and two hours, but with the small kids I would like to avoid any hassles. Thanks...
