As long as the reservation was made at least seven days before the departure date, travelers may cancel their flight reservation within 24 hours of making the purchase and receive a full refund under Air France 24-hour cancellation policy. This policy is applicable to all flights operated by Air France, including those purchased through outside travel agencies or websites. It's a practical choice for travelers who need to alter their trip itinerary immediately after making a reservation. Travomonk has further details about this policy if you want to go deeper.
