Going to Nassau. We will land in Atlanta at 940 out an hour later to Nassau will we go through customs in Atlanta or Nassau? Do we have time?
There is no US Customs when leaving the US. You will go through Bahamanian Immigration and Customs in Nassau. If your first flight is domestic all you have to do in Atlanta is go from your arrival gate to your departure gate. You have enough time.
I have a very early flight 7:00 am with hour and fifteen drive time to airport. how early should I arrive at the airport?
With checked bags get there at at least 5:30. Without checked bags you could get there closer to 6. Note that this is the time to walk in the doors. If you have to park, you need to add on time for that.
