Jet Blue cancelled my flight after I had boarded. They attempted to rebook me for a new flight two days later. I was able to rebook with a different airline, but not until the next morning. As such, I was forced to get an expensive hotel and missed important work meetings Monday morning. I am very disappointed with the customer service and will be pursuing full reimbursement for my hotel cost.

Flight delayed 4 times on a non-stop from BOS to SFO. Then when landed in SFO had to wait for 30 mins for a gate AT 3:30AM.

Horrible - for the first time in my life i was denied boarding an international flight because the name used on my ticket - Josh - was not exactly the same as my passport - Joshua. At no time during ticketing, online check-in, or at the airport flying from Boston to NY was i notified of a problem. It was only at boarding from NY to Costa Rica I was informed of the problem and by then it was too late. After missing the flight I was told by airport Jet Blue staff, including a supervisor, that it was my problem and they could not assist because i bought "the cheapest fare". i was hung up on twice by JetBlue customer service, including once by a supervisor. I blame Kayak and your awful partner ChatDeal for even allowing me to purchase an international ticket without verifying this - you effectively sold me a ticket i could not use. Shame on you and shame on ChatDeal for doing nothing to help me resolve the situation. What a scam.

The flight kept getting delayed, but the ground crew did not communicate well to the passengers in the terminal. First, we were told that it was an engine issue. That was understandable. We asked, after the third delay, if it would be canceled; they reassured us that that would not happen because a new plane was on its way from Washington DC. Four hours later, that is exactly what happened. No announcement was made only people who had the JetBlue app learned of the cancellation. They rebooked us on a flight that would get into our destination 36 hours after our original time I had to spend an exorbitant amount of money to book an additional flight with a different airline, the following morning in order to make it to my conference in time. Not to mention the fact that by the time I discovered the cancellation on the departures board, it was too late for me to receive a refund on my lodging in the destination city for that night. Because I had booked with KAYAK, I did not receive any JetBlue email with rebooking information. This is what the information information desk kept telling everyone who inquired about a rebooking. This was my first time flying with JetBlue. Needless to say, after extremely poor communication andover $1000 of additional expense later, I will not be flying with them again.

We were several hours delayed due to confusion during boarding. Evidently the crew could not match the manifest with the boarded customers. After significant time trying to find individuals on board, a crew member walked through the entire plane re-scanning each of our boarding passes. Then we had to wait for a new slot to depart, and when we landed, our gate was not ready. It was a complete goat rodeo from start to finish.

Horrible. Flight was cancelled, jet blue app not working to rebook, no phone number available to call Jet Blue, 400 ish people in line for the help desk, stuck in Boston for 2 more days had to book new flight with a different airline and still not sure if I will be able to get any refund.

Flight was delayed many times. The crew was friendly but you eleven had to buy headphones to access the movies in the plane. $8 is not a lot for one person but it is when you travel with all your family.

The food took two hours to be delivered to my seat, when I'm on an overnight flight I want to sleep asap after take off

Flight left 2 hours late with no explanation as to the delay

I like everything. Blythe at DCA is the absolute best!
