New policy for JETBLUE at JFK terminal, lifted text below from their site:
Last Updated: 10/22/2015 7:07:00 AM EST
This week, JetBlue will be testing a new way to pay for flights and fees at the airport. Beginning Friday, October 16, 2015, cash will no longer be accepted as a form of payment at the ticket counter.
Customers wishing to pay for their flight, fees, or services, will be able to convert cash to a prepaid credit card at a convenient ReadySTATION kiosk for a fee of $5 USD. These prepaid credit cards can also be used anywhere credit/debit cards are accepted, including in the terminal and onboard your flight to purchase food, drinks, movies and other products in our cashless cabin environment. ReadySTATION kiosks are conveniently located next to the JetBlue kiosks used for check-in and our JFK airport crewmembers will be available to assist with the conversion.
