Expedia itself typically does not charge extra cancellation fees. Instead, any fees come from the airline, hotel, or travel provider. Some hotels offer free cancellation, while others may deduct a night’s stay if canceled late. Airlines often have strict fare rules outside the 24-hour grace period. To confirm whether your booking will incur fees and how much, call 866-204-0803 and an Expedia customer support agent will explain your cancellation costs clearly.
