Whether Expedia will refund you depends entirely on the specific cancellation policy of the airline, hotel, or car rental company you booked, as Expedia acts as an intermediary. Most flight bookings offer a "High-Fidelity" 24-hour cancellation window where you can get a full refund if you book at least seven days before departure. Beyond that, if you booked a "Non-refundable" fare or room, Expedia generally cannot override the provider's rules to give you cash back, though you might receive an "Expedia Credit" for future use. For hotels, many listings offer "Free Cancellation" until a certain date; if you cancel before that deadline, Expedia will process a full refund to your original payment method. If you purchased "Cancel for Any Reason" protection through Expedia, you can usually recover 70% to 100% of your costs. Always check your "Trips" page on the Expedia app to see the specific deadline for your booking, as missing the cutoff by even one minute can result in a total loss of funds.
