To cancel an Air France award ticket (booked via Flying Blue), you can generally do so through the "My Bookings" section on the Air France or KLM website, or via the mobile app. Under the 2026 Flying Blue policy, reward tickets can be canceled or changed up until the check-in deadline for the flight. Most standard reward tickets incur a €50 (approx. $55) cancellation fee per person; once paid, all of your Flying Blue miles and any taxes/fees paid in cash are refunded back to your account and original payment method. If you are a Flying Blue Ultimate or Platinum member, this fee is often waived. It is important to note that once the flight has departed or if you have already checked in, the ticket typically becomes non-refundable. For complex bookings involving partner airlines (like Delta or Virgin Atlantic), it is often safer to call the Flying Blue service center directly to ensure the miles are successfully redeposited.
