I was flying to MEX from LAX and i had to get through customs which took a long time, but got to the Aeromexico ticket counter to get my boarding pass and they told me that they start boarding 45min before departure time and I got tot he counter at with 35 min to departure and they told me that I missed my flight and had to buy another flight which was two hours later. I don't understand why they couldn't let me through or hold for me. It ruin my ground transportation reservation which I had to reschedule. The whole thing was frustrating and cost me more money that what i thought i was saving.

They had good movies in the plane

There were two runways in Mexico City and one was under maintenance so it took a long time from the moment we landed to the time we were able to get out of the plane. Then, they took our check-in luggage from the plane and it went through an inspection (bag by bag), so this caused another hour delay. After that they gave us our check-in luggage for us to take it to another location (to another floor) within the airport to be checked-in again. They wanted to charge us $20.00 additional per check-in bag even though they were half of the weight limit. After we complained, they dropped this charge. Due to all the delays we lost our connection and we had to book another flight. Not a good experience. We will never make a stop in Mexico in the future.

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.

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.
