For international flights, Air France has a check-in rule that stipulates customers must show up at the airport at least three hours before to departure. This rule gives enough time for procedures like security checks, baggage drop-off, and other formalities. In addition, travellers can check in online or through the Air France mobile app up to 30 hours before their departure time. To avoid waiting in queue at the airport, check in online. For a hassle-free trip, keep in mind to examine the Air France Check-In Time International Flights guideline.
