Yes, Expedia has a refund policy+1-877-738-0617, and one key aspect is the right to cancel within 24 hours. If you have booked directly with Expedia and notice a mistake with your booking after making the payment, you can cancel your flight and claim a full refund without penalty, up to 24 hours from when the original booking was made. This applies as long as the booking was made at least 7 days before your scheduled departure.
