There was a huge glitch in your ticketing, resulting in me confirming the same ticket 3 times. After calling Jetblue for customer service per your advice, they first suggested to give Jetblue credits for extra tickets. When I insisted that the issue was solely caused by kayak-jetblue ticketing connection issues, they supervisor approved to cancel 2 credit card payments... BUT I have to wait for 2 weeks to see the cancellation on my credit card. Unfair and ridiculous, if you as me.

Seat pitch on the plane unbelievably cramped. When seats are so close that if you drop something on the floor you have to be a contortionist to get it, you know it's a problem NEVER fly the 787-900 economy.

On the way back there were open seats with extra leg room and I asked the gate attendant if it was possible to switch my seat to one with more room and they said they only could if I paid extra.

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.

If you have more questions or if you have a bad price to report to us,
