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.

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.

Lost luggage. The Aeromexico Rep at the departures desk was mildly helpful. She told me the person I need to speak to was busy and that I should go downstairs and wait by McDonald's. She said i should sit, because it could take a long time. She didn't ask my name nor tell me who I should be waiting for. Just to wait. I had to ask for the persons name I should be waiting for and if she would be wearing a AM suit. I asked if there was a desk where she would be, and with an attitude the Rep, said "I already told, you just go wait by McDonald's". After waiting for an hour and asking every woman that walked by if they were Stephanie, I finally found her. She was walking by, clearly not looking for me. I had to follow her and stop her. If not she would have walked right by. Once we spoke, she was very helpful.

That was one of the bad moments I experienced with Copa once.

Terrific Gate Team in Houston, who were extremely helpful with my current disability (my foot is in a walking boot). Gate agent immediately approached me once I got to the gate (via wheelchair) to see if I needed anything else. Then she took it upon herself to move my seat so that I had an empty row on the flight to prop my leg up on the flight, which was excellent customer service. She anticipated my needs & exceeded them. She signaled for me to board early, so I had enough time & space to get down the ramp. Gate agents like her are hard to find these days. I wish there were more agents like her. Flight to Indy- Plane were more spacious between the seats. My knees had 6”-8” between them & the seat in front of them. It was a new plane, so if this is the direction that United is going with their aircrafts, they will have lots of happy flyers.

It was recommended to download the United app for free inflight Enterainment once I purchased the inflight WiFi. After purchased, none of the movies or tv shows would play. It seemed like slow WiFi was making it impossible to utilize the Entertainment promoted by United.

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.
