You can check in online for Air France flights starting 30 hours before your scheduled departure. For flights departing from the United States, such as Atlanta and Detroit, online check-in opens 24 hours before departure. The online check-in process is available on the Air France website and mobile app, where you can enter your booking reference or Flying Blue number to check in, select seats, and download or print your boarding pass. If you have checked baggage, you must drop it off at the airport baggage drop counter. Passengers with only carry-on luggage can proceed directly to security and boarding after online check-in. It is recommended to arrive at the airport at least 3 hours before international flights and 2 hours before domestic flights to allow sufficient time for check-in, security, and boarding. Online check-in may not be available for some bookings, such as codeshare flights not operated by Air France or flights with special travel restrictions. Passengers traveling with infants, unaccompanied minors, or those requiring special assistance should check in at the airport to ensure proper arrangements. Airport check-in counters generally open 3 hours before departure and close about 45 to 60 minutes prior to the flight, depending on the airport. Using online check-in helps reduce time spent at the airport and allows for a smoother travel experience. Always verify your flight details and check-in times before travel, as they can vary based on destination and booking class.
