Getting to ATL without losing your buffer

- Off-airport parking and rental-car facilities add a transfer step before check-in.
Inside Atlanta Airport
- ATL's domestic and international terminal areas feed a large concourse system. Leave time for check-in, security and movement to the gate.
- The Plane Train speeds concourse travel, but waiting, walking and escalator time still count.
- Airline bag-drop deadlines and international document checks can become the binding constraint before security.
