The outbound crew was terrific. The flight itself was fine. We even arrived early.

Upon deplaning in Cancun, ALL passengers are put on a bus and driven far away from the terminals to an arrivals area. Those of us with connecting flights are royally f*cked at that point, especially if your connection is short, as mine was. The so-called shuttle to the departure terminals, which are entire kilometers away, was to arrive in like half an hour. HALF AN HOUR. Who has this time to spare?? The alternative to the shuttle is paying a taxi that charges a hefty fare--and God help you if you don't have cash. The departures terminal was swamped and only thru begging assistance and line cuts did I make my connection...and then only by the skin of my teeth. It was a complete nightmare.

The overhead bin did not stay down low enough so that I could place my bag in. It would lower then before I could place my bag raise slightly by a few inches. For someone of my height (5’5”) that was problematic. Fortunately another passenger saw my dilemma and held the bin lower to its full opening capacity. This also momentarily slowed down the boarding process.

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.

Terrible customer service both on the phone before the flight, but Especially from the gate agent. Wow she was really horrible.

The flight attendants on board were good! They helped get everything straight. Easily could have been handled by the incompetent gate agent. Wow.

Delta did a really good job as always. Cheaper, more comfortable, and a WAY better experience than Alaska Airlines.

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,
