Air France typically does not offer cash refunds for non-refundable tickets. However, they do provide travel vouchers that you can use for future flights. If you booked a non-refundable fare and need to cancel, you can easily apply for a travel voucher, which is valid for several months.
To request a voucher, log into your account on the Air France website, locate your booking, and select the cancellation option. Air France will issue a voucher, which can be redeemed on a future booking. If your flight was disrupted or canceled by the airline, you may qualify for a full refund instead of a voucher.
