paying any applicable fees as well as the difference between the price of your new and old flights.
Additionally, travellers can cancel their flights with jetBlue for free for 24 hours, and a complete refund will be automatically applied to the original payment method. This implies you can cancel your ticket for any reason up to 24 hours after booking and get a full refund with no changes or cancellation fees. You can cancel your flight by going to jetBlue.com's My Trips, selecting "Start Flight Cancellation," clicking "Need to Cancel?", and following the instructions. Passengers will have the chance to review the specifics of their flight and confirm that they would like to cancel before the cancellation is finalized. The location where the ticket was purchased does not have to be the destination for cancellation requests.

Basic Economy fares and other fares that originate in specific markets are subject to cancellation fees. The following are the JetBlue Airlines cancellation fees: $500 for all other international flights, $200 for flights within the JetBlue States, $200 for flights to Canada, and $300 for flights to Mexico, the Caribbean, and Central America. Most of the time, basic economy tickets cannot be changed, but travellers may be able to cancel with a cancellation fee as mentioned above and use the remaining amount, which will be issued as an eCredit, toward a subsequent jetBlue ticket.
