Expedia’s cancellation policy varies depending on whether you booked a hotel, flight, or package. Many hotels offer free cancellation within a certain window, while flights depend on the airline’s own rules. Expedia generally honors the 24-hour cancellation rule for flights, meaning you can often cancel within a day for a full refund. After that period, fees may apply. Always check the “cancellation and refund” section in your itinerary. For help understanding your exact booking terms, call 866-204-0803 and an Expedia representative will assist.
