There were multiple delays but JetBlue tried to make the boarding and departure process as quick and efficient as possible. The crew was as detached from reality as could be, meaning: not very friendly and just doing things by the numbers.

There were multiple delays but JetBlue tried to make the boarding and departure process as quick and efficient as possible. The crew was as detached from reality as could be, meaning: not very friendly and just doing things by the numbers.

Jetblue needs to improve on Onboarding as it seems to always be behind on departing. It never leaves on time. I would recommend to have an earlier Onboarding in order to leave on time and respect your customers time as well.

40 minute delay before take off after boarding flight. Bright lights throughout night flight due Issues with light panels. In flight Entertainment nonfunctional

I booked this flight using JetBlue points and I was just so happy. The plane was so clean, I had every need met. Thank you!!

Another horrible Jet Blue experience. This airline has suffered the biggest decline of all from best to worst. TVs didn’t work (again). internet was temperamental. Boarded late and couldn’t get organized to serve snacks.

I hate their constant delays! It’s as if I cannot confidently make plans for timing when I'm traveling with them. I slept through it, so all I can say is it was good.

The staff at JFK were rude and unhelpful. I was harassed for the same bag that I used on my flight to jfk with no issues claiming it was the inappropriate size. The women then allowed my travel companion to board with the same size bag because they thought she was more “humble”. Also on the flight when informing the flight attendant that nationals no longer have to fill out the Bahamas immigration form my statement was met with eye rolling and attitude.

One of the crew members, a male complained about my bag being too heavy, which I felt was really unnecessary. I am disabled and would have carried it myself if I thought it was going to be a problem. In addition the landing was rough because everyone gasped in unison which it touched down.

There was no wheelchair or wheelchair escort at the gate..unacceptable

Surly, unhelpful ground staff at JFK. There was a complete lack of empathy—a flawed check-in ordeal caused us to miss our flight. All airlines that I have ever flown would have worked to help me solve the ticket problem. Instead, frontline employees shrugged their shoulders and pointed fingers at us for having made an error. I will do anything to avoid EVER flying on Jet Blue again. It well deserves its low rank among airlines.
