Whether you can change your flight on Expedia without a fee depends on the airline’s policy and the type of ticket you’ve purchased. Most airlines charge a fee for flight changes, especially for non-refundable or basic economy tickets. However, if you have a flexible or refundable ticket, you may be able to make changes at no additional cost or with a lower fee. In certain situations, such as flight cancellations or major travel disruptions, airlines might waive change fees. To explore your options, log into your Expedia account, go to “My Trips,” and check the details of your booking.
