Flight was delayed an hour due to a flight plan issue. Then additional fuel was needed. The crew did communicate well. Upon departure there was not food available for purchase, at least not by the time they got to row 23. Wifi didn't work consistently. Not the normal Jetblue experience. The Captain and crew were great though.
