Atlanta’s airport is very busy, and TSA/security lines can be long at peak hours.

Common guidelines for Frontier flights from ATL:

• Domestic flights: Arrive at least 2 hours before departure
• International flights (if applicable): Arrive at least 3 hours before departure

Morning and late afternoon are often the most crowded, so give yourself extra buffer if you’re:

Frontier Check-In Area and Baggage at ATL

You can:

🧳 Local tip: If you’re being picked up curbside, tell your driver whether you’re arriving at Domestic North or South. Even though baggage claim areas link inside, it can save time to meet at the correct side (Frontier is tied to South).

2. Ride the Plane Train to Concourse D.
3. Exit at D and go up the escalators/elevators to the gate area.
