Once in the plane everything was fine.

Plane was delayed by 2 hrs.going , and returning from destination. JetBlue is not reliable. It is happening more often. On top of that they charge more when you need to check in a luggage. For the price, Delta is so much better, and you do not have to pay for check in luggage. For that reason, I will try to stop flying JetBlue, and fly DELTA. REFERRED DESTINATION: SANTO DOMINGO.SQR

On time departure and early arrival. Excellent cabin crew - very attentive and generous with snacks. Reliable free wifi.

I couldn't get a seat assignment ahead of arrival at airport without paying for an Even More Space seat. Then I ended up in an exit row with no window. Not cool JetBlue. I'm a longtime True Blue member and MasterCard holder; you'll be hearing from me about this.

We flew high above a lot of weather and had relatively little turbulence; the landing was very smooth.

The boarding gate is tiny and has almost no food available and not enough seats. The TSA line was closed. My seat and the floor around it were filthy with sticky white stuff, adhered to the black leather. Clearly the area had not been cleaned.

Boarding was very organized and quick. Slight delay taking off but not bad for JFK. Lovely crew. Bumpy flight but the captain kept us informed. Food better than expected. Flight arrived early but no gate so we had to wait.

OMG! The seats are obnoxiously close together. I could only sit perfectly upright and even then my knees were pressed tightly against the seat in front of me. I am only 5'7". Impossible to rest due to lack of space. I tried to put my head down on my tray table but couldn't since it hit the seat in front of me. Mid flight my 13 year old daughter got back spasms. Upon arrival we could barely walk and looked like two old women limping down the jetway. No idea how a tall or larger person could have even sat down.

There was no communication as to why our boarding process was delayed 1 hour. Clearly there was USPS mail being unloaded but no communication was offered until 45 minutes after our initial board time. It does not bother me the flight was delayed, it was unprofessional not to offer any communication.

I had to change seats as my wife had surgery while we were away, Delta made that happen with little fuss. Seating was quite good.

Prices are per person, are for e–tickets and include all taxes & fees in GBP.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller
At KAYAK we don’t set prices, so it’s not possible for us to guarantee what other companies are selling.

We aggregate tons of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we don't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car hires can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find on occasion that certain prices are no longer available.

More questions or if you have a bad price to report to us
Please send us an email and someone from our team will get back to you promptly.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days. Fares are subject to change and may not be available on all flights or dates of travel. Some carriers charge additional fees for extra checked bags. Please check the carriers' sites.
