To manage your Air France booking, go to the “My Bookings” section on the airline’s website or mobile app and log in with your booking reference and last name. From there, you can change flight dates, cancel your reservation, or add services like baggage, seat selection, or meal preferences. Most changes can be done online, but fare rules and fees may apply depending on your ticket type. If your ticket isn’t changeable online, contact Air France customer service directly for help. Always review the updated fare conditions before confirming any modifications.
