Frontier Airlines offers multiple check-in options to accommodate travelers' preferences, each with specific guidelines to ensure a smooth journey. Online check-in is available starting 24 hours before departure and closes 60 minutes prior to the scheduled departure time for both domestic and international flights. Passengers can check in via the Frontier website or mobile app by entering their reservation code, ticket number, or ConnectMiles number. During this process, travelers can select or change seats, add baggage, and obtain a boarding pass, which can be printed or saved to a mobile device. For those traveling with checked luggage, it must be dropped off at the designated bag drop area at least 60 minutes before departure. 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 requiring 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.
