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

Flight was ok

The flight was actually run by turkish airlines, not philippine air as stated in my confirmation email, so we were sent to the wrong terminal. Nothing in the email said which terminal the flight would depart from or that it was actually turkish airlines. Very irresponsible and communication for customers should be much clearer. Luckily we were very early for the flight or it could have caused a serious problem.

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 !!!

Nothing.

The service was not great which surprised me for swiss. The flight attendant was absolutely not into work. The seats supposed to work.. wasn’t .. we had to switch the seats with no help and with the lights off. Awful .. of course they didn’t noticed so they didn’t woke me up for the breakfast. (And I’ve been asking for). Maybe was bad luck but that’s really ridiculous. During the flight they didn’t brought water or something we had to call them.

I'm 6 ft 2. Legspace was adequate, and no silly boxes under the seats like other airlines that obstruct your feet. Great entertainment systems - modern, good selection. Food and staff excellent.

Their online checkin systems could operate a bit more smoothly. At one point, I had to go in in person, because the online checkin site had an already past flight from their codeshare partner SAS showing up as the next flight, and I couldn't perform online checkin as a result.

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.
