I booked a flight through Travelocity, and the flight was changed by more than 24 hours. Should I request a refund from Travelocity, or from American Airlines?
I'm a US citizen flying from China.
You should request a refund from Travelocity.
Airlines may not be able to help you here.
Although the airline may offer full refund, there may be change/cancellation charges by Travelocity.
