What is the cancellation policy for Expedia Flights?!{!{In-Depth Guide}}

Canceling a nonrefundable fare will result in an e-credit for the full amount paid (minus any cancellation fees, depending on fare type and route). However, if you cancel a refundable ticket, you’ll get the amount paid refunded back to your original form of payment.
After 24 hours: If you cancel after the initial 24 hours, your chances of getting a refund are slim, unless you have a refundable ticket. 24-Hour Rule: Many airlines offer a full refund if you cancel within 24 hours of booking (1-800-205-9716), as long as the booking was made at least seven days before departure.
