The flight attendents were fabulous, very friendly and helpful. I sat in the first row and when I boarded the attendant helped me find a spot for my carry on luggage.

I paid for priority boarding but never had the chance to board early.

The destination, the time and direct flight.

When I got to check in at the airport I found out I had to pay $100 per bag. This was never told to me when booking. I was also made aware that if I had booked my bag when I checked in on line each bag would have been 75$ . Of course I hadn't checked in on line and this was a huge surprise.

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.

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.
