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.

They were very dishonest about everything. We need to be there in Australia on Monday morning for very important event but reached Australia Monday night 8PM. Virgin Australia contatcted out their flight from SJC to LAX through Delta and Delta cancelled flights becaue no-show of Pilot to operate the plan. What a Joke???? We asked them to put us through another carrier to LAX for connecting flight they refused.Very very BAD. It was a big miss for us.. never again Delta/Virgin Australia..............

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.

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.

We were able to pay the extra $30 per person to get premium coach seats. The extra leg room made all the difference and the seats even seemed to have more lumbar support than usual. Crew was full of smiles. We've never had trouble with checked bags on Alaska and this flight was no exception.

We think those who carry on should have to pay for that luxury! Maybe it would get rid of that mess as people are getting settled upon boarding the plane.

The plane took off over an hr late due to lack of heat and the pilot had to reboot the system, once the plane finally took off the flught attendsnts then explained they would start the beverage service but were iut of most options and we could get ready to pay for what was left, maybe if they offered complimentary beverages at that point would've been a nice touch.

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.

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.
