Frontier Airlines provides multiple check-in options to ensure a smooth travel experience. Passengers can check in online via the Frontier website or mobile app, starting 24 hours before departure and up to 1 hour prior to the flight. To check in, travelers need their reservation code, ticket number, or ConnectMiles number. During online check-in, passengers can select or change seats, add baggage, and obtain their boarding pass, which can be printed or saved on a mobile device. For those traveling with checked luggage, they can proceed to the designated bag drop area at the airport after completing online check-in. It's important to note that certain passengers, such as those with special needs, unaccompanied minors, or those traveling with pets, may not be eligible for online check-in and should complete the process at the airport. Additionally, travelers with outstanding payments or reservations that require additional documentation must check in at the airport. Frontier Airlines recommends arriving at the airport at least 2 hours before departure for domestic flights and 3 hours for international flights to allow ample time for check-in and security procedures.
