Review the fare rules associated with your ticket. Go to Priceline.com and click on the "Check Your Request" link. You will need to enter your email address and your trip number. Your trip number was included in the email you received from Priceline confirming your purchase.
Click on the "Ticket Changes and Cancellations" link in the "Important Information" section. If the fare rules for your ticket allow changes and cancellations, the airline will give specific fare rules and restrictions and the cost for changes.
If changes are allowed, review alternative flights and fares offered by the airline on the Priceline.com website. If your itinerary includes more than one airline, search for flights on the airline whose name appears on your original credit card charge. Your new itinerary must include at least one flight on that airline.
Calculate the fare difference between your old itinerary and your new one. If your new flight costs more than the original flight, you will be required to pay the difference. If your new flight costs less than the original, you will not receive a refund for the difference. Some airlines will apply the difference to the change fees or provide a voucher toward future travel. Contact the airline directly for more information on this option.
Call Priceline at 800-774-2354 at least one hour before departure or check-in and inform the representative that you want to change your ticket. Be prepared to provide your new preferred flight information, your reservation number, your email address and your billing information.
