They weren't thinking about our safety and security in getting us home. We got diverted to Baltimore when we shouldn't have taken off in the first place, the second time. And we were left with no safe options to get home!

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.

American Airlines lied to us that this flight was canceled. They made me go to the ticket counter to book another flight. While standing in line, my husband found out it was not canceled, but they were boarding the plane. The porter that pushed my mother in the wheelchair was able to get our bags checked. No American Airlines employee would help us. They just said to go back to the end of the line. The porter called the gate to have the plane wait for us. American Airlines DISCRIMINATES especially against the elderly!

Flight wasn’t bad for what I paid for. One MUST definitely do his/her homework before flying to be prepared for all of the extra costs, etc... I was glad I did and was prepared with my own food, neck pillow, etc. I didn’t expect much in terms of creature comforts and therefore wasn’t disappointed. There isn’t much space in the cabin, so I was glad to have my 6-year old in between us 2 adults. Crew was pleasant r and professional. Ticket agent was helpful if a bit “assertive”. I probably won’t try to book them for long flights, but for short flights their fine

The tiny space and small seats!

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.
