Every single employee I interacted with was awesome.

Over 5 hours in delay due to a maintenance issue. Problem wasn't discovered overnight when it was parked. Wasn't discovered until the next day. Had to wait for the delivery of a specific part and install it. I'm all for planes not breaking upon reentry, but the fact that the two flights were both subsequently delayed 4-5 hours each instead of bringing in a sub plane was inconsiderate. Now I've got a long drive home and I'll only get an hour of sleep before a 14-hour work day. So thanks for that, JetBlue

Up to expectation; on time, smooth check in with kiosk, efficient and courteous TSA security line, clear navigational sign, bookstore, clean windows, clean seat, and clean air.

waiting area after security checkpoint is a little too tight at West Palm Beach International Airport.

The attendant on this flight was very nice. many times and to get on a flight with United the attendants seem like they don't want to be there and they don't want you to be there. But this man was genuinely joyful to each customer.

The boarding process was ridiculous having five flights leaving out of one gate in five minute increments is very confusing this could definitely be better organized

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,
please send us an and someone from our team will get back to you promptly.
