I’ve flown SWISS Air twice in the past 6 years and I’ve never had an issue, always a great experience!

It was very efficient and the staff was very nice. The line was long but fast. The seats have quite the lean which made it easier to lie back. Getting Swiss chocolate is always a plus.

The seats weren’t as comfortable or fluffy but it was a short flight so it can very well be overseen.

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 !!!

On board entertainment ststem has lots of options to choose from on all accounts. Food selection was good, served hot with large selection of drinks. Overall much better than US airlines that cross Atlantic.

More comfortable seats for long haul flights is a must have. Comfort+ Offered a money’s worth alternative to business or first class. Boarding is done away from terminal building which required busess for transportation back and forth. Prefer skybridge instead.

Absolute nightmare dealing with British cancelled flight and then having them rebook me with American, their "partner" company. Spent three hours this morning dealing with these two unprofessional companies and their lack of communication between each other.

This seems like an old plane. Poor quality of screen to watch movies and very small selection of movies. No charging spot to plug and charge our phones. This was a long trip and these two elements are important to make the trip enjoyable.

Announcement was made that flight was delayed for at least two hours and that delay might be longer or might be cancelled. Desk staff specifically said they would not help rebook until the 2 hour delay had passed. I bought a ticket on Delta amd actually flew to London.

There was condensation leaking from the ceiling of the cabin. A crew member said this was normal, would have been nice to know this ahead of time to reassure me that for a first-time overseas flier that this is normal.

Nice crew

I booked a LATAM flight for a 10.5 hour flight specifically because they have better in flight entertainment. I arrived at the airport and found it it was operated by AA. 10.5 hours with zero in flight entertainment. HORRIBLE EXPERIENCE.

Wonderful flight

The only thing I didn’t like is that he have any fresh food they said something was going on in LA that prevented him from giving us actual food other than that everything else was fine

Almost everything. Only the food was lacking. I like their new planes. The outlet at the seat in coach. The magazine options at the seat as well. I did not look at the entertainment so I will not rate that. The crew was professional.

Just the food options. Ginger snaps was what was served for food and a beverage. I suppose this is what obtains on most airlines these days but can't I hope for something more like maybe a sandwich? AA has the opportunity to set themselves apart in this area.

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.
