Expedia’s cancellation policy allows travelers to cancel most bookings within 24 hours of purchase for a full refund, provided the travel date is at least seven days away. This applies to flights, hotels, and car rentals, giving customers flexibility shortly after booking. For flight bookings, you can cancel or modify your reservation within 24 hours without fees, as long as the departure is more than seven days out. Hotel and car rental cancellations follow similar rules, but not all bookings may qualify, especially nonrefundable fares or special promotions.
