I didn't know Frontier charges for everything but water. $3 for peanuts, $3 for coke and more for anything else. That is ridiculous for a 4 hr flight. They charge $40 for a checked bag and $45 for a carry on if you pay at checkin, or $60 if you pay at the gate. OUTRAGEOUS!!! The seats DO NOT recline. And the worst of all is they wanted me to sign up for their miles club and credit card...not gonna happen

Nothing really.

Boarding process was horribly handled. Food was inadequate. Stewardess was saccharine. Bathroom door didn’t shut completely. I was told this wasn’t an international flight and therefore no free alcohol. Aero Mexico flight to Mexico City had much better food, free alcohol and more attentive service personnel. Also delays because of equipment problems.

Due to the earthquakes, the film festival I was going to was cancelled. Ten days prior to the flight I called AeroMexico to cancel and they said there would be a cancellation penalty, which was fine. When I tried to redeem my credit, they said there was also an additional "No-show fee" even though I called to cancel 10 days prior, which left a total of $70 credit after all their penalties. I called and emailed to complain but they did nothing but pass me to someone else who was equally unhelpful. I will never fly AeroMexico for any reason 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,
