I couldn't get a seat assignment ahead of arrival at airport without paying for an Even More Space seat. Then I ended up in an exit row with no window. Not cool JetBlue. I'm a longtime True Blue member and MasterCard holder; you'll be hearing from me about this.

The Cancun airport provides a terrible experience for transferring between flights, especially if you need to change from the international terminal to a domestic terminal or vice-versa. There is no way to get between terminals inside security and the free shuttle is slow and overcrowded. Meanwhile, one is forced to run a gauntlet of taxi and shuttle drivers trying to get you to pay them exorbitant fees to drive you to your terminal. Once you finally arrive you discover that there is no dedicated baggage recheck for an international arrival. Just don't buy a ticket that transfers in CUN.

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,
