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..............

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.

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,
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.
