Flight was as expected. But it was delayed an hour. Also, my luggage got damaged. So that sucked especially since the damage made navigating the airport difficult. Walking to get ground transportation is sooo far away now and my checked bag was difficult to carry.

Flight was as expected. But it was delayed an hour. Also, my luggage got damaged. So that sucked especially since the damage made navigating the airport difficult. Walking to get ground transportation is sooo far away now and my checked bag was difficult to carry.

Flight team was very courteous only complaint wS the boarding process and mandatory bag check

It was a great flight got here on time wish they would give headphones out for free

The flight was delayed 4 hours and the JetBlue people at the counter kept lying to us and telling us it was due to weather however all other flights were going in and out of NY and FL. Then they lied that the plane had to stop to refuel. Then they lied and said the plane needed a tire change. JetBlue is the worst. Then they gave a lot of people meal vouchers however I didn’t know they did that and they didn’t offer anything to me.

Disaster This is why I stick to delta You get what you pay for

I had a great experience flying with JetBlue and would always choose JetBlue over the other airlines. I am also very bummed that they will discontinue flying to Belize very soon. SAD

I was traveling with two small kids and our TV s were the only ones not working. Informed the flight attendant who did nothing about them.

I was especially impressed without efficiently the crew got passengers on and off. One of the stewards was slightly gruff, I thought. No big deal but that's what I noticed.

Delayed our flight to accommodate another flight but didn’t make the decision to do so until we were supposed to board despite having all the same information hours prior. Arrived so delayed that we didn’t get a gate and had to deplane on the tarmac and get bussed to terminal in the rain after 1am. Arrived to the terminal and due to construction could not get a ride share - had to either take the air train to Howard beach or stand in line with 200 other people waiting for a taxi.

Well, its a hit or miss when boarding most of the time your employees just let everyone enter immediately In one bum rush. Then out of know where tell the passengers only let A can enter then b then c etc. So make a decision and stick to it. Do it by alphabet and have famn strick compliance. Let the public know. That makes easier on passengers.
