Airline reviews

The gate and ground staff were excellent, friendly, went out of their way to acknowledge my Mosaic status. The plane was an older Airbus, so the seats were a little worn. The in flight attendant was not very nice, and seemed to be annoyed to be at work or be on this flight. Flight was fast and we landed early and pilots kept us informed.

The gate and ground staff were excellent, friendly, went out of their way to acknowledge my Mosaic status. The plane was an older Airbus, so the seats were a little worn. The in flight attendant was not very nice, and seemed to be annoyed to be at work or be on this flight. Flight was fast and we landed early and pilots kept us informed.

The inflight system with their wifi is a hot mess and doesn't work. Separately they do, but when you try to do theoretically simple things like pair a device for control it all falls apart

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

The flight was delayed for 4 hours. Once onboard the crew was wonderful.

I rate it is good we had a 4-hour travel delay at one point but JetBlue gave out food vouchers and travel points credits for another flight so they try to make up for it

Did not enjoy this flight at all. All of my coworkers flew delta and I chose JetBlue because I really value how simple the WiFi and entertainment is and this flight I didn’t get either. Crew staff was unsympathetic to my system not working, everyone I asked for help with was extremely bothered by my request for help.

Little snafu at boarding. Staff communicated with gate poorly. Flight attendant was rude making disembark early. This was an older mint class. Needs an overhaul for sure. Food was good. The male flight attendant was really nice.

Like the space, did not like the snack options, there was no power outlet in seats, no entertainment, no flyfi.

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.

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.
