Air France allows passengers to check in online as early as 30 hours before the scheduled departure time of most flights. This applies to both the website and the mobile app, making it convenient to choose seats, confirm travel details, and obtain a boarding pass in advance. The online check-in service is generally available for all Air France-operated flights, but some exceptions apply, particularly for codeshare flights operated by partner airlines or certain departure airports that do not support online check-in. In those cases, passengers must check in at the airport. For domestic flights within France, passengers are advised to arrive at the airport at least two hours before departure, while for international and long-haul flights, it is recommended to arrive three hours in advance. The check-in counters at the airport usually open between two and three hours prior to departure and close approximately forty to sixty minutes before the flight, depending on the destination and airport. Baggage drop-off closes around the same time, so passengers who check in online should ensure they arrive early enough to drop off checked luggage. For example, on flights departing from Paris-Charles de Gaulle to international destinations, baggage drop may close 60 minutes before departure. After checking in online, passengers can either print their boarding pass or store a digital version on their mobile device. If traveling with only carry-on luggage, they may proceed directly to security without visiting the check-in counter. However, travelers needing special services, those with oversized baggage, or those traveling with pets or infants should go to the check-in desk even after completing the online process. In addition, Air France provides self-service kiosks at many airports for quick check-in and boarding pass printing, available for use within the same time window as online check-in. The airline emphasizes punctuality and advises all travelers to be at the gate before boarding closes, which is typically fifteen to twenty minutes before departure. Failure to comply with check-in or boarding time requirements may result in denied boarding. For connecting flights or itineraries involving multiple airlines, passengers should confirm whether a separate check-in is required. In most cases, if all flights are booked under the same reservation and are operated by SkyTeam partners, check-in for all legs is possible at the start of the journey. To avoid issues, travelers should always verify check-in deadlines for their specific flight, as rules can vary depending on the route, airport, and destination. Being aware of these timelines and following them closely ensures a smoother airport experience and reduces the risk of missing a flight.
