Emirates cancellation policy allows passengers to cancel their flights up to 24 hours before the scheduled departure time. Passengers can cancel their flights online or by contacting the Emirates customer service team. If a passenger cancels their flight within 24 hours of booking, they will receive a full refund. However, if a passenger cancels their flight after 24 hours of booking, they may be subject to a cancellation fee. The amount of the cancellation fee depends on the fare type and the destination.
