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.

No forced charges for checked-in and carry-on bags-BIG differentiator ! used 787 Dreamliner.

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,
