It was hot and not as comfortable as the flight to Chicago. Must have been a different plane that needs to be worked on or replaced.

It was hot and not as comfortable as the flight to Chicago. Must have been a different plane that needs to be worked on or replaced.

The SFO lounge closes at 12 midnight. My flight took off at 2AM

It was extremely hot in the cabin the entire flight, vent air was worn

Have not had a flight out or returning to Norfolk that has not required maintenance, and a gate delay. Properly staff the crew so maintenance can be performed without last minute emergencies on each flight and there is enough staff to have gates prepared for inbound flights. Staff to ensure the safety and on time service vs. profit.

We were forced to eat vegetarian food because non veg food ran out. The breakfast was mediocre.

My original flight was cancelled and that affected my trip and my plans and I got no compensation and customer service was hard to reach as well

The kid in the middle seat kicked me almost the whole flight, almost kicked my hot tea off my tray. The flight was delayed due to the first plane not being able to be de-iced in July! We had to get a new plane. Now I drive 3 hours back to Edmonton because direct flights from PVR were way to expensive

The flight was delayed by a hour and I wish they had communicated it sooner. No issues on the plane, it did take a while for food to come.

Know that the movies that you are going to be offered are the oldest be rated movies they could possibly get. They may have one or two new movies that they keep advertising but when you’re flying 15 hours, there is nothing to see past the first new movie.

Agents at gate were not immediately available to solve problems and once they did they didn’t fix all the fight connections

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

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.

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

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

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

I usually dont fly JeTBlue and I dont think I will ever do it again. The flight was delayed fee time, nobody was giving us any info at at the airport, gate changing, the slowest and poorly organized boarding ever, rude staff.. huh

The flight was delayed. I upgraded to more room. I can't imagine how small the regular seats are I haven't upgraded for my return flight yet.

see my previous response about being kicked off the flight and having to fly the next day, ruining a planned vacation tour.
