Concourse F:
MARTA–
Q: How do I get from the Domestic terminal to the <<International>terminal?
Depending on your airline, there are two options.
If your airline does not allow you to check in for your international flight from the domestic terminal, there is a free shuttle service outside Baggage Claim. The shuttle operates 24/7 and in 15 minutes it delivers you to the departure level of the International terminal.
If your airline does allow you to check in for your international flight from the domestic terminal, then you may ride the Airport’s “Plane Train” to the <<International terminal at Concourse F>>.
