Flight was fine, but I was annoyed to have to pay for luggage again. We had paid for our luggage on our first two connecting flights with SATA Azores Airlines, but had to pay for luggage again with JetBlue at JFK airport. For one trip we paid over $500 for two suitcases to travel from Azores to San Francisco.

Terrible. Quality has gone down significantly. Plane was delayed. No instructions from the staff. Will try to avoid in the future!

Thought the economy premium experience would match that of the Amsterdam to Boston flight. Aircraft was older: chair didn’t lean back. I had to buy a blanket, which on the flight over was complimentary. Flight crew seemed disinterested all around.

The plane was filthy and worn - the seat pockets were stuffed with tattered food and torn pamphlets. The cleaning crew that came on as we were deboarding were grabbing handfulls of trash and perfunctorily wiping down tables with dishrags. It's been a while since I flew Jetblue and it used to be a great experience. After this flight I will avoid flying Jetblue again if there is any alternative.

JFK is the worst airport and JetBlue is the worst airline

A more comfortable seat. Padding would be really helpful but I've read the airlines don't want customers to be satisfied with economy seats.

Great price, easy check in, love the free drinks and snacks, and nice crew. The only negative part was waiting for your seat assignment 5 minutes before boarding, and the seats are a bit uncomfortable.

It took an hour to get my bag after landing. Not exaggerating

Everything was good instead change the gates! I missed my first flight because it was changed the gate and I didn’t know!

almost 4 hour delay as they over booked and had to wait for 8-10 volunteers to agree to travel next day.
