The economy seats are more comfortable than average transatlantic flights on other airlines, albeit far from perfect. The meal was nicer too. The crew both onboard and on land was nice and attentive.

The entertainment system is slow and the selection of films to watch could be better.

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 !!!

Flight way delayed 3 hours. Staff gave no information and wouldn't help rebook us onto other flights. They gave us food vouchers 2 minutes before we finally boarded, so we couldn't use them. The food on the plane had spoiled so we were all starving on the flight, and we all missed our connections. Horrible experience and wouldn't fly with KLM again.

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!

Leg room. Direct flight from Europe. Drink services were a lot better than our outbound flight.

Plane was incredibly old for a long haul flight, with no power socket and extremely outdated TV's. Seats were dirty and small. We were in row 34 (middle of the plane over the wing) and when they got to us with the food options, they had already run out of the second choice on both occasions. On the first service, we asked the attendant if the food had any fish/seafood ingredients (due to allergies) and she said no. We then read on the lid of the food tray that there was a possibility of fish traces so my husband could not eat it. When we told the attendant about it she told us they didn't have anything else. Hard to believe there was nothing they could do, we've never experienced this issue before. We then asked another flight attendant if there was any food available for purchase but she said no. Luckily, she was able to find a vegetarian dish that my husband could eat. We're grateful that she found this as the next food service was not until 6 hours later. Sad that we had to ask again, we were expecting that they cared a little more. Overall, BA didn't meet our expectations unfortunately. This was a trip to Europe in which we took 4 BA flights and overall, the experience was of that no better than a low cost. Would have a hard time thinking of choosing this airline again.

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.

All the normal stuff of flying domestic.

The way that my brand new suitcase was damaged on the flight and BA just said that handles are excluded from bag damage. Thus, they can do what ever they want with your bag's handles, manhandle it and not take any responsibility. My suitcase was clearly damaged by the way it was handled since i booked it in till i received it again and they just said sorry...there is nothing we can do for you!!! Now that is is poor customer service.

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. Fares are subject to change and may not be available on all flights or dates of travel. Some carriers charge additional fees for extra checked bags. Please check the carriers' sites.
