Pros: The crew were very friendly and attentive, there was a delay to boarding and departure but they were very apologetic about it. Service was attentive on the plane and bags promptly delivered at the baggage carousel.

Cons: I upgraded at the airport to Executive class, which is really a bit of a scam to be honest. It’s just the first two rows of the plane and the middle seat kept free... the seats were no different to economy. Not worth the 109€ upgrade fee.

Pros: The inflight entertainment was top-notch. Plenty of choices, good quality and the touch screen responded well to touch. Boarding was quick, efficient and pleasant.

Cons: Cabin crew servie was somewhat lacking during the flight. We got our drink before dinner and the drink cart did not come back again when dinner was served so we had to have dinner without a drink (other than the small cup of water that comes with the tray). Breakfast now has been relegated to a breakfast bar - really?!?!

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.
