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

Nothing.

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.

Flight attendant was nice. She changed my seat to the front cause the guy behind me was kicking my chair.

They cancelled my flight from the day before and when they rebooked my flight, they could of gave me a better seat.

Everything went smoothly.

The row I chose for a seat was next to the bathrooms. Those seats don’t recline. Found it it’s very hard to sleep sitting upright. That made the flight and the first day of my international trip difficult. It would be nice for the sites seat selection feature to include such nfo on seats. I paid nearly $2000 for a shitty seat.

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

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.

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.
