The person in Aeromexico balcony didn't have training to attend clientes in the best way. She didn't know how to add miles to my number of fidelity and she told me that she can't change my seat to the aisle, because the sistem was not working and her english was very poor too... Very poor service.

huatulco airport is small and easy to navigate. only needed to arrive 50 mins before departure even with luggage. the flight was comfortable and less than an hour with a complimentary drink (soft drinks, coffee/tea, alcohol).

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.
