- each seat has cable television (even for very short flights) - I was asleep my whole flight from Long Beach to SFO but the pilot was great! came over the speaker to let us know there was a great view of the sunrise and what we were flying over below. - dimmed the lights for the flight since so many people were sleeping on the early flight

The seats were really bad, it was our first trip on a 787 and I will never do it again. Not as bad as the Airbus from MIA but considering it's 13 hours it was totally rubbish. We normally fly the 777 with Air NZ, after this we will go back to them. The staff, as always were helpfull and pleasant, the plane was quiet but the seats.....

The flight had no pilot assigned to the flight yet the attendants still boarded us. Then we waited on the plane for an hour before exiting the plane. The attendants gave us little information on flight alternatives and when the flight was finally allowed to board again, they did not announce it and so had I not been waiting close by, I would have missed my flight. It was extremely disappointing but not shocking with all the scandals that have occurred this year with American Airlines. I do not recommend flying with them.

No one knew I was deaf as crew knew on way to NY. Not sure why this happened.

I am deaf. Ticket going to NY stated deaf and this return said nothing on it. Plane had no air, just heat. Steward was excellent during flight and kept offering front of plane water. Very unpleasant. Poor guy was sweating serving drinks/food. He was a gem.

Our prior flight arrived 30 minutes late and we had to run to the opposite side of the airport. We were there before the departure time but the staff gave us a hard time saying they were going to lock the doors on us. It wasn't until the flight crew ran up behind us that they finally didn't have an attitude and said we were fine. Online entertainment didn't work, no shows, the map doesn't have a time or useful info. My row was skipped by the crew for snacks. The guy came from behind first, which I didn't see and then one the way back, he didn't even look at my row or the row in front of me.

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.

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

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.
