A Jetblue Airbus A320-200, registration N534JB performing flight B6-137 from New York JFK,NY (USA) to Santiago (Dominican Republic), was climbing through FL330 out of New York when the crew initiated an emergency descent due to the loss of cabin pressure, the passenger oxygen masks were released. The aircraft levelled off at 10,000 feet about 6 minutes later and returned to New York for a safe landing on runway 13R about 65 minutes after departure.
A replacement A320-200 registration N569JB reached Santiago with a delay of about 4.5 hours.
