Correct Carol. No jetway for us on AA to Miami. We, per usual, went to identify our gate so we'd know where it was (we were quite early) and I was disappointed to find it downstairs and so crowded and hot. We went back upstairs to wait it out, and luckily checked BACK downstairs earlier than we thought necessary, as they were moving everyone out to the bus to begin boarding earlier than I would've assumed.
I recall some questions a while back about options for getting downstairs as mobility was a concern for someone - there's a stairwell as well as a rather large elevator.
