between lunch and supper snack one isle had only one water serving and my isle had none. So for 6 hours we had no water serving. This is why I gave crew rating OK only. Also the supper pizza snack was horrible. By comparison, United gives full drink cans so they last longer. I suggest Lufthansa also should serve full drink cans in long flights.

I bought 2 tikets from Chicago to oscow and back for me and for my son. I live in USA, son lived in Russia but he received immigration visa and I had plan fly to USA with him. From Chicago I used my ticket and say SWISS staff what my son will have trip only from Moscow. I paid for 2 tickets around $1700. Today when we should have trip back to USA, SWISS company said what ticket for my son do not exsist. And I spent for new ticket 220000 rubles about $3600. Nobody in SWISS company do not said me what my tocket for son canceled. I am shoked !!!

Poor food, and very little of it is given. poorly run airline. Too many unnecessary rules that don't apply to any other airlines that they claim to be in the name of security. Will not fly again.

Showed up 3 hours before departure and still missed our flight. The agents were extremely slow and rude. If you have a giant line of people who have missed their flight your system obviously isn’t working. Avoid Heathrow’s British Airways by all means if possible.

See / hear the middle-aged guy around seat 22 aisle coughing his lungs out throughout the 10 hour flight without once covering his mouth ? WTF is going on w an airline that would let a passenger behave like this ? Didn’t see the attendants offering a cough drop, or asking if he would please behave like a civilized human being. Looking for others corroboration. Spread the word like this guy this w his germs

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,
