I liked the flight attendant in first class. Unfortunately I was not in first class

I did not like the attitude of the obese old man (I, too, am an obese old woman) as I saw it toward some of my cabin mates.

The snacks were decent on the flight. Everything else was a disappointment.

Unexpected delay for take off after being told the flight was going to be on time. They couldn’t give us a reason or an eta on take off while waiting at the gate which affected my ride situation once I landed in Seattle.

Our pilot was excellent. Best flight considering the weather while flying over Colorado. He was informative about the turbulence beforehand and did a great job steering through or around most of it. Typically I hate flying.

The crew was wonderful - professional, thoughtful, and lively!

The seats were so squished that it was difficult to get comfortable, especially on an overnight flight. Alas, this is now true of all air travel.

Good selection of films as usual.

I had to put up with *loud* banter from 2 flight attendants at the back of the plane throughout the entire flight, which was freakin' annoying to say the least. I'm NOT interested which pilot or male attendant you find cute or want to make out with. You also really shouldn't laugh at passengers' faces after telling them to resume their seat to the upright position. A real shame since their performance "on the floor" was perfect.

the flight attendants and service were amazing and perfect. The green tea from All Nippon Airline was awesome.

All the food were terribly salty, inedible because the beef was hard like rock, I was unable to eat or chew. The sauce was salty and terrible so threw them away. In general, the food were inedible and poorly prepared that means they were not considerate and discreet about cooking, selecting material,too. The airline only pick the terribly cheap meat to scam and mistreat the passengers. I felt I was ripped off and sadden.

Crew was friendly and responsive. Gate crew kept passengers informed of the delays. Flight itself was ok.

Flight ETD was 8:25 but plane developed a mechanical problem. After about 20 minutes waiting for maintenance the Captain decided to go back to the gate for fuel and repairs. After maintenance came on board the decision was made to deplane. Finally, a plane from Chicago was scheduled to take us to San Diego. After boarding at about 12:30, it was discovered that catering never loaded food. We waited for over an hour for food to be delivered. At close to 2pm the Captain, who kept us aware of what was going on, asked us if we would agree to leave without a full delivery of food, and all agreed. So by 2pm we were finally enroute to San Diego but having a seat in the back meant we only got to eat what was left, which for me, was a small cheese pack.

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.
