Flight was on time arrived at the destination 10min early they kept in touch via email

The best flight I’ve had in a while. The plane was like 25% capacity, if that. Smoothest boarding and deplaning process I’ve ever experienced. Wish all flights were this smooth.

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.

Great! I love Jet Blue. My favorite airline! Very efficient, clean and timely.

Going through JFK’s security is a mess. The TSA security said no shoes on the bins. So, we place our shoes in the belt and they came out all over the belt. Boarding was delayed and Flight as well.

The best experience that I have had traveling with JetBlue!

at the time for boarding the lady just call Group A and no other goups and everybody from A to F go inside without the right turn,and when we get in theres no more spsce for carry on , the ones that get in at not correct group from the back occupy our space !!!!! a mess !!!!

Nothing. Jet Blue is a great choice for me And I’m going to miss flying with them Since I travel to Lima Peru very often 😞😞😞

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.

Great crew. Smooth flight that was on time. Boarding is a disaster as usual. Bought more room seat and was Grouo A. The flight was packed by the time I got on. TVs did not work as usual

Waited for our plane from HNL so we didn't miss connection. AMAZING Service for that, then really clean plane. Nice airline attendants.

Good even though flight was delayed, the crew was prompt and efficient.

My flight was completely full. Making me very stressful with people walking around all the time. I believe airlines can do better for entertain people during the flight.

Flight was on time, crew were excellent. For some reason our originally selected seats were changed. We had to re-choose our seats when we checked in online and options were limited. One of our two checked bags we placed on the wrong carousel. It was only be shear luck that I saw it. That cost us 20 minutes of wasted time. So much for the “priority” tags. They are meaningless, and have been ever since they were implemented. I wish you would do the save some money and stop using them.

Everything was very good. Was able to change a make run flight leaving on direct earlier in the app -seamless!!! Well done

Moody attendants that can barely look up at the passengers. I’m all for people having an off day, but you can tell some Untied Airlines Employees have lost their zeal for their jobs

Being stick waiting for gate at ORD cause me to almost miss my connecting flight…being deaf United made no no effort to keep me updated as I couldn’t hear the PA

The passenger in the row in front of me was listening to a political speech on his phone at full volume with no headphones and it was disturbing all of the passengers around him for several rows. I asked 2 of the flight attendants to speak to this passenger but they only shrugged. It was obvious that they were afraid there might be conflict and would not say anything. I had to take it upon myself to tell the passenger that he needed to turn it off or wear headphones as it was disturbing everyone around him not wearing their own headphones. I was very disappointed in the United flight attendants.

Slight delay but not bad. UA app worked well! Got regular updates of gate changes, etc. Don't have any complaints.

Onboarding process was great and efficient. Plane was very new and entertainment choices were great. The only complain is no meal despite it was a flight that is longer than 6 hours.
