Food and drink service not given. There was no turbulence to justify this failure, and flight was over an hour long, allowing sufficient time to provide it. Poor communication of departure delay.

My flight to Lima was delayed therefore I would miss the connecting flight to LAX. I learned of the delay by overhearing a conversation the employee was having with another passenger. No announcement was made, no options were presented to help the passengers with connection find a solution until we started demanding a solution. This ordeal started at 9pm and we did not make it out of the airport till 1:50am to a hotel for a 6am pickup back to the airport to start the process all over again.

They were unable to check my bag through my final destination thus I had to clear customs, secure my checked luggage, and recheck. If the agents had responded to my situation and taken charge, I would have made my connection.

Nothing

They charge you extra fees for a carry on bag if the people decides it! I flight with the same airline from mx city to denver and they charged nothing while from denver to mx city they charged 25 dollars with the same suitcase! Also delta gives you free basic wifi while this guys charge it extra. Btw they take away all your carry ons amd make you to wait for hours to get them back! They dont have automatized check in so they make you wait for long time in the row.

Boarding was very delayed. The flight was very delayed. There was never an explanation or acknowledgememt, of the delay and it seemed no effort to make up the delay while in the air. As a result, a great number of us missed our connections to Boston. Poor effort by AeroMexico and Delta

Friendly staff and useful network connections.

I hope when they finish renovating the Mexico City terminal, they install some moving-sidewalks. I waked quite a bit with my luggage.

Normally, getting on a plane in Colombia is an absolute nightmare. People pushing, standing right next to you, when you get on the plane all the old women who do not know how to read always walk to the back of the plane when they're supposed to be sitting in seat 7? Been there? Seen that? Yes ! Seen it a million times. What makes this particular flight so unbelievable, and maybe it was just a training day because there was a lot of airline personnel at the check in kiosk, but I have never processed on to a flight in Columbia, given up my baggage, and be walking to the gate so fast in my life! I truly hope this is something that will become standard, and I pray to God that the other airlines especially Viva will learn how to do!

Overall very good, good crew... minus point.. seats SO tiny, it makes Asian airline economy seats feel like 1st class!

When you connect out of Mexico City, the food is always fresher and more protein-rich. Yum!

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.
