Online check-in is available to Frontier Airlines Atlanta Terminal passengers up to 24 hours before to their departure. There are manned check-in counters and self-service kiosks accessible in the terminal for individuals who would rather check in at the airport. Checking and carrying on baggage are subject to costs under Frontier Airlines' special baggage restrictions, so it's important to familiarize yourself with the rules before you travel.
Passengers head to the security checkpoint after checking in. To facilitate the management of traveler flow, the Domestic Terminal features various security lines. Passengers who qualify can speed their screening process with TSA PreCheck. The gates are easily identifiable and have clear signage, and boarding usually starts thirty minutes prior to departure.
