Whether an Expedia booking is "really refundable" depends entirely on the cancellation policy of the individual hotel or airline, not Expedia itself. Expedia acts as a marketplace, so if you book a "Non-Refundable" room or "Basic Economy" flight, Expedia cannot override the provider's rules to give you a refund. However, Expedia does offer a "Cancel for Any Reason" (CFAR) add-on for select flights during checkout. If you purchase this, you can usually get a refund (often minus the fee for the CFAR product) if you cancel at least 24 hours before departure. Additionally, many hotels on Expedia offer "Free Cancellation" until a certain date. In these cases, Expedia is very reliable at processing refunds back to your original payment method. Always read the "Rules and Restrictions" section carefully before paying, as a "refundable" booking often carries a slightly higher price than the non-refundable version.
