Frontier Airlines operates its international flights from Terminal South at Hartsfield-Jackson Atlanta International Airport (ATL), rather than the dedicated international terminal. This means all Frontier passengers, whether traveling domestically or internationally, will check in and depart from Frontier Airlines International Terminal Atlanta. International travelers will go through customs and immigration procedures in the same terminal before boarding their flight. The terminal is equipped with self-service kiosks, check-in counters, and baggage drop areas for added convenience. After clearing TSA security, passengers can enjoy a variety of dining options, shops, and comfortable seating. It is important to check flight status and gate information frequently as international flight procedures might differ. Make sure to arrive early and allow enough time for customs and security processing.
