A popular pass that gives jetBlue customers unlimited access to the skies is once again taking flight.

You could say Brooklyn residents Scott Castle and his fiance Deborah Bencosme are stooping to new lows to fund a month’s worth of travel on JetBlue with the All-You-Can-Jet Pass.

“We made this snap decision to buy two of them on a credit card and 20 minutes later we looked at each other and realized we don’t have the money,” Castle said.

The unemployed lovers are doing what any young couple filled with as much wanderlust as time might do — selling the contents of their apartment via a stoop sale to drum up the cash to finance their flights of fancy.

“We were thinking of every city we are going to, eating the typical dish of the city,” Bencosme said.

Scott and Deborah are now part of a rabid community of more than 6,000 mostly youthful, tight-fisted passengers who purchased the passes to anywhere JetBlue flies from September 7 to October 6. Passes went for $500 or $700, depending on the restrictions, for travel that would otherwise cost thousands of dollars.

“Last year over 50 percent of the customers who bought the passes had never flown JetBlue before. But since the pass last year we have tracked the number of people who have continued to fly us, and how many existing customers have flown us more, and both of those metrics, we are very, very happy with those results and that’s why we’re doing it again,” said JetBlue Senior Vice President of Marketing Marty St. George.

Partly to claim he will finally have visited every one of JetBlue’s airports, Chelsea resident Seth Miller says he is doing it again.

“I am a huge fan of the flying aspect of this pass. So far, I have booked 25 flights over 30,000 miles, through a couple of weeks and still have a couple of weeks to play with,” Miller said.

The excitement over the JetBlue passes has created quite a fervor on Facebook and Twitter, breeding an organic society of like-minded travelers who are either flying or following those who are.

“The community itself has decided we want to organize, we want to be social, in addition to going on all these trips,” Miller said.
