You should be fine. I've never flown AF
but even if it takes you an hour to clear customs and get your bags, 2 hours will still be more than plenty of time. The worst I've had at ATL
from the time I entered the queue at check-in, passed through security, and arrived at my gate was about 1.5 hours, and that was the Friday morning of Labor Day weekend. My average at ATL
is usually well under an hour from the time I get out of the car (assuming drop off) to when I arrive at the gate.
Heck, a couple of times in two hours we've managed to drop the luggage off at ATL
and check-in, drive to Ft. McPherson and park the car there (save $8 or $9 a day for two weeks trips) then ride the MARTA back to ATL
, clear security, and arrive at the gate with plenty of time.
In other words, assuming no delays, you'll be more than fine. If you find yourself needing to kill time, go to the Chili's Too in the A-Concourse (up one more level) and request a seat by the window. Allows a great view of Delta ops on the ramp between Concourse A & B.
