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

Great experience. Boarding was fast, staff were very nice and funny, everything at the seat worked well.

Horrible! Several delays and then was cancelled! I spent over 24 hours in the airport and was unable to get a hotel or food voucher.

It was perfect! United Airlines staff was extremely caring, super friendly and professional

Smooth travel. Immediate update prior flight delay so I can arrange myself properly without too rush.

Boarded early; and arrived home 40 mins early. After a long flight, it’s nice to be back home early. These flights have no amenities; no snacks. So need to bring your own

A long delay. Don't travel late in the day.

Food is very bad and entertint not too many options ... flight attendet service is not good

For a 17 hour flight, they kept us well feed. The music selection could be better curated. The entertainment selection was about what is expected. The crew was fantastic.

I forgot to pre order gluten free on a 16 hour flight and I am pretty sure the crew raided their own lunches and first class to keep me fed.

When I agreed to give up my two seats because of overbooking by the airline, I should have been offered some sort of reward or credit towards a future flight. I was not. It was not until the next day when I mentioned it to a Jet Blue employee that I was advised to call 1-800-JetBlue. So here I am, having done Jet Blue a favor and I had to do the work to find out if I was going to get a credit. Such service

A nightmare. Scheduled flight delayed 2 hours then cancelled because pilot timed out . Unable to find another pilot. Really?! Weather certainly a factor, but JetBlue seemed totally unprepared for the chaos that ensued when flight routes were cancelled. More cancelled flights, finally many of us who had been bumped from other flights were allowed to board a Boston bound plane around 3:00am, delay after delay, sat on tarmac for another half hour while pilot dealt with weight distribution issues (?), arrived in Boston 4:30. Crew were wonderful- same attendants all day and night and they were exhausted. Fortunately for me and my son that Boston was our final destination, not so lucky for many who missed connecting flights.

Complete and total debacle from start to finish. HUGE mistake picking this airline. NEVER again! Rudest staff in the business.

The food took two hours to be delivered to my seat, when I'm on an overnight flight I want to sleep asap after take off

It's not JetBlues fault but there was a smell on the plane (possibly other travelers) and 3 children behind me that never quit whining. Soccor fans that were very loud. Pilot brought the plane down from high altitude quickly, dropping us hu dress of feet at a time. I've never felt that intense of dropping on other airlines (usually fly Southwest Airlines). But I arrived safely and I'm thankful for that.

Seats were great, the staff was great, and the food was about the best I've had on a plane, and is especially the best of any US-based carrier I've flown. Free Wi-Fi was also great.

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

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

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.
