The seats were roomier than other airplanes I’ve been on.

Checking-in in Barbados was excellent, connecting in JFK to JAX was a nightmare, had to wait over 1 hour and 20 minutes to receive my check bag. After receiving my checked bag and going to the gate to check in for my flight to Jax the crew there had no clue. They first told me that I had missed the flight and had to rebooked.. after trying to speak with JetBlue reservations (without luck) I was asked to leave my Phone number for a recall, I did so and my call was returned after 15 hours. I finally looked at the information board and saw the flight that I was originally scheduled for was still at the gate. I alerted an JetBlue employee of my findings and was told to rush to the gate and see if I could still board. The agent at the boarding gate apparently was having a very bad day, after lecturing me on how late I was (which was not a fault of mine) let me on the flight. A VERY BAD EXPERIENCE. I will NEVER fly JetBlue ever in my life again.

The boarding gate experience was good, however they were too exact at checking

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.

Domestic flights are good. Just stay away from international travel

Jetblue provided a very good service during the flight, the plane in a very good condition, the crew is professional, everything was on time. That's it!

The regular feedback of any changes to our flights. The Jetblue staff were very helpful. Our flights were great. Lots of leg room!

They delayed our flight by 45 minutes and then re-updated the departure time back to normal schedule with no notification, email, or app update causing probably 40 people to miss the flight as they left without us.

We liked the flight, but not in JFK, not in Gatwick it is no lounge and this was surprising and disappointing. I think by now it is understandable that COVID will not go away and why it should not be business lounge?

The service was very good, will use the airline again.
