Late — this was delayed 5 times, meaning I was unable to get to a morning meeting. No explanation was given. No advance warning given. Delays on the way to Phoenix as well. Terrible airline.

Stewards were attentive and if needed extra they got it for you. Flight was clean and the legroom makes a big difference then the major carries legroom which is nothin. And the fact we took of a few minutes late but arrived exactly 48 minutes early was a big surprise after the cross country flight.

We loved anything. Direct TV was down on flight but still had one channel of XM and three movies that were just in studios. So was able to watch two movies to pass time.

Price looked good at booking.

Old prop plane was grounded 5 min. after our boarding time. Went to several gates to try to hop on another flight but nothing got me to my destination in time -- so a total loss. Tried to cancel by phone (line to gate service was 50+ people deep), and was told I couldn't cancel. Then was told I could. Then was told I had to call back! TOTAL LOSS. Refund is needed.

Crew was friendly.

My flight was delayed twice on both the trip out and the return. It's not such a bit deal for a longer flight, but when the flight is barely more than an hour and it's delayed for an hour each time it really starts to negate the point of flying instead of driving when you factor in the airport time.

I love JetBlue. I love everything about the airline. I love the free wifi and snacks. The seats are comfortable and I actually have room to lay my head down in economy. I love jet blue so much I am always willing to pay extra to fly with the airline. The customer service is superb and I have never had anything but an extremely possitive experience with this airline.

Nothing to complain about at all. Overall a great airline

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

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 the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes 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 can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals 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.
