Frontier Airlines Atlanta Terminal provides travelers with multiple easy ways to check in. Online check-in lets you select your seat, pay for your luggage, and print your boarding ticket up to 24 hours before your departure. Self-service kiosks and manned check-in counters can be found in Terminal N for travelers who would rather check in at the airport. To guarantee a seamless check-in and security screening procedure, it is advised to arrive at the airport minimum of two hours prior to your scheduled flight. Once you've checked in, head to the security check. To speed up the process, Terminal N includes multiple security lanes. There is a separate lane for expedited screening for travelers who have enrolled in TSA PreCheck. Ensure that your ID and boarding permit are prepared to be shown to security staff.
