We like being able to check our ski equipment without extra charge. Service is consistently professional and courteous.

Being charged for seat selection. The late hour of departure for the Boston to Zurich flight.

Easy, quiet boarding and flight, USB port available, audio and sound were working, nice movie selection. Friendly and helpful crew, assisted with cough crisis

Seats from JFK to Zurich were a little bit squeezed.

We (parents) were business class, but our two kids in coach, yet Swiss doesn’t allow “guests” in the lounge. Hmmm. What a bunch of BS.

Excellent 8.0

Cabin crew were friendly, efficient, courteous Refreshments generous and excellent. Good movies.

Rather than boarding economy passengers by row number, there is a free-for-all at the gate, and tedious blockage in the aisles as passengers wait for others to place carry-on luggage. More leg-room than United, but still a bit crowded for tall people. VERY BAD DESIGN of arm-rests, which do not go up all the way into the seat but instead jut out at an angle.

Flight was an hour and a half late boarding, sat on the tarmac for 45 minutes, and there was no offer of complimentary beverages. Very barebones level of service.

The plane ride was excellent and boarding , ... was great. The class is not too crowded.

The 8 seats per row in business class is very crowded and the practicality of it is far from optimal. The food is not much of a culinary experience

The water bottles, pillow, and earbuds were on the seats.

The returning flight to the US they did not dim the lights so that it was comfortable to sleep. A red light was shining down on my head most of the trip because I had a window seat. It was very annoying.

The flight from EWR to Oslo was delayed by over 2 hours which meant I would miss my next connection... and I understand that happens sometimes. But, it was after hours on the airline number phone number and the fly.com customer service could not help with finding an alternate connection from Oslo to FRA. It was frustrating to then have to wait at Oslo airport for another 4 hours before the new connecting flight.

Virgin Atlantic continues to give great service. Their lounges are way above all other airline lounges. It is difficult to get well prepared and fresh fish in lounges, but Virgin Atlantic knows how to do it.

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,
