When I booked, I included my checked luggage and when the bill was sent there was no record of this. Its was costly since I am from Trinidad amd Tobago. Exchange rate over seven dollars to one US dollar.

When I booked, I included my checked luggage and when the bill was sent there was no record of this. Its was costly since I am from Trinidad amd Tobago. Exchange rate over seven dollars to one US dollar.

Everything was good except checking bags . I had paid for two bags but it didn’t show so we had to do it again while people waited and we were struggling to get to our flight

Plane was delayed multiple times. I would like to request a refund. Was due to arrive Thursday evening ended up arriving Friday morning.

The crew and the pilots. The pilots were amazing. The landing in Cancun was excellent.

The security line at JFK was one of the longest I’ve ever experienced - probably 45 minutes. I don’t know if JetBlue has control over it, but it detracted from the overall experience. Entertainment had good options, but the volume control was a bit small to tap on and the screen had a fair amount of interference blips. Clearer picture would have been better.

I liked the entertainment on JetBlue, the service from JFK to JAX was terrible at best

All the TV screens in my rows was non functional . The map shown for an international route was antiqued..

Excellent price. Everything on time. two bad parts. Kayak said I couldn't sign in for the flight online, but I got an email at the same time from Jet Blue and they let me sign in online. Second bad part was that, although I had provided my known traveler number, neither of my boarding passes, for this flight and the previous one, had TSA pre-check showing.

In-flight staff was very helpful and excellent. However, the flight was delayed by 90 minutes. Also the boarding process should be expedited in case of delayed flights. This will help the passengers trying to make international connections.

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.
