The flight was delayed 14 hours and communication was very poor. No one seemed to know what was happening and the gate agent was trying to help people for several flights. She was by herself trying to help 100s of people.

Domestic flights are good. Just stay away from international travel

Every time I leave from sti Dominican Republic, there is always a delay with a flight , causing a rush to make it to the next flight considering you have to go threw immigration

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

I will NEVER fly with this clown show airline again. Idiots. All of them. Unprepared. Unfriendly. Miserable employees. NEVER. EVER. AGAIN

For whatever reason, I could not check in online. Kept getting the "It's not you it's us" message. Even when we tried the kiosk at the airport - same results. The check-in person had a very difficult time getting our boarding passes together despite the fact that we could show confirmation on the jetblue website. After a very long time we finally got boarding passes. The only other issue is, my vegetarian meal featured chicken.

The aircraft was fine, it’s was just the service. The flight got canceled several times and that was very inconvenient for my 69 years old mom.

My checked in luggage cost was $59, almost ticket price. The first 13 rows were empty, but fly attendant did not alow women with little boy change her middle sit, sweet boy was crying, I am so sorry for mother and passengers. At the end of the flight the cabin became impossible cold. Only good was timing of departure and early landing, but it suppose to be normal.

I tried to book a flight with Jet Blue. Your third party company hijacked my attempt with a website that looked like I was booking with Jet Blue. I realized it when I paid. I tried to cancel and was told by a man in India that there were no refunds. $735 stolen, Thanks Kayak!

It was inexplicably canceled and we are stuck in LA, haven't gotten home and it has been an inconvenience having lost work (on unpaid leave for my husband).
