My Swiss flight to JFK was cancelled before 24 hours without explaining the reason. They should explain the reason at least. I had to take an another flight and arrived at JFK after 6 hours from the original flight. My trip was totally messed up, so I was not happy at all.

There was water to drink

Plane felt like a 1990 air France flight. Cabin dated. The least amount of room I can remember on a plane. When sitting upright and the person in front reclined, i looked at their head and if I crossed my arms, it would touch the seat in front. Could not pick up pillow that dropped on the floor, could not bend around the seat in front. Very hard to get out to use the toilet. Felt very claustrophobic.

Flight left almost on time and arrived on time. Crew was friendly.

Wasn't able to select a seat ahead of time like with other airlines. Seat rows way too tight (even for a normal 130 lb person like me). No good movie options, very limited selection. Food pretty bad, but that's almost expected this day and age.

Flight cancelled due to overbooking, notification received while I was en route to the airport. Was assured I would be on the flight for the following day. Awoke next day and called airline to confirm, they stated my refund had been processed, I would not be on the flight, and there was nothing that they could do for me. I was forced to rent a car and take a completely different flight from another airport at a much higher price. Never again.

This airline is disaster. They trielt live on the planet don’t give a &$!@ Made us buy new tickets for the following day for a type o on the ticket. They just didn’t care...

They kept me and my two year old in the plane for almost 4 hours and told us that we will take off every ten minutes, but obviously we never did. We got rebooked for the following day. They provided a small room to stay in and $7 wach for food. They treated us like a huge inconvenience. We had to pay for food, my husband had to take another day off work to come get us. This airline is shameless. We are spending more money to with a different air line next time.

Don’t give a single glass of water for free. It’s $4 if you get thirsty on an international flight. Disgusting and should be illegal. Not to mention the cabin smells like urine/fish. And for whatever reason this airline attracts a crowd that leaves a lot to be desired. There were several fights on my fight. Never again.

Prices are per person, are for e–tickets and include all taxes & fees in GBP.

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 prices, so it’s not possible for us to guarantee what other companies are selling.

We aggregate tons 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 don't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car hires 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.
