NOTHING.

Cheap flight sounds great...except it’s not actually cheap. Once you add on charges for baggage, seats, water on board, etc., it’s about the price of a standard ticket on a quality airline. (Plus they didn’t actually reserve the seats I paid $20 for, even though I have the receipt). Amenities on board are atrocious. No Wifi, no in flight entertainment (except an iPad you can pay $25 for that features 10 movies from 1992), no USB ports...you even have to pay for water!!! My flight was delayed twice in one week causing me to miss my connecting flights both to my destination and back home by 5 minutes. Because they are not a member of an airline alliance, my only options were to wait until the next day and stay in a shared hotel room or rebook on another airline for $600 which they couldn’t guarantee I would be reimbursed for. The general apathy shown by the staff and lack of communication is abhorrent. The least they could do is apologize and help direct me to somewhere I could find more information. They were positively clueless! Spend a little extra and book on a respectable airline that values their customers...and maybe you won’t be out $1200 (in addition to the cost of the “cheap” tickets) like I am!!

We did not ask for refunds or even hotel reimbursement we simply asked to be booked on the next days flight to Pittsburgh and WOW refused making us purchase new tickets for over $1000.

From pre-boarding, to boarding, to the food, and the attentiveness, everything was top notch! The cleanliness of the plane was only topped by the friendliness of the crew.

The flight was marked at almost 11hrs but ended up being only 9...not a negative other than it meant not spending as much time on board!

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

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 !!!

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.
