how to change Name on Expedia flight ticket

Fees Expedia doesn’t charge a flight cancellation fee. However, the airline might charge a fee to cancel, depending on the fare type purchased. If this is the case, Expedia will pass this cost on to you. You can see the airline’s fees, rules, and restrictions for your flights in your Expedia itinerary. After 24 hours:- Just like any flight booking, Expedia flights can be cancelled more than 24 hours after purchase. However, you may or may not get a refund, depending on the type of fare purchased. Even if your booking isn’t eligible for a refund under Expedia’s flight refund policy, you still may be able to get a credit from the airline. If you’re not sure what type of fare you bought, check your itinerary for airline policies and rules.
