Pros: Helpful crew. They reset the screen, came around with blankets, headphones and generally tried to make the space habitable.

Cons: When I am asked to book my seat, I am usually shown a map which has no reflection on the overall reality. The seat I select is normally allocated to me but if the plane is not full (unusual) I am told there are unavailable seats that would provide more choice.

Good 6.0

Pros: This particular flight was parked at the closest bay to immigration at Heathrow. So a late boarding and arrival was made early through not having a mile long walk to passport control.

Cons: Disorganized boarding with the plane load of people huddled around the entrance to the boarding area. No guidance from the crew on how to efficiently pack the overhead bins efficiently with passengers helpless to put their treasures into the overhead bins.

Okay 4.0

Pros: Seats offered decent space and crew was nice.

Cons: I called the airlines and requested a special meal, and was only provided it one-way so was left unable to eat anything. Water was free, but would only give you small amounts and was very infrequent. Waiting in the queue to check luggage took over an hour. There were only a few attendants, and at one point all attendants left except for the one that was checking in flight attendants. Awful.

Excellent 8.6

Pros: Better staff than normally, which was both surprising and pleasant. Flight made it on time for the changeover in Zurich, which is very important.

Cons: Extra charge for luggage - it showed up in the itinerary only after everything has been paid for. And even the paid suitcase allowed 23 kg only. It has been just over TEN years ago that you had two suitcases at 32 kg each included in price! Does the airline seriously believe that you can travel around the world with just a swim trunk in your pocket? This policy is an insult to any world traveller. We do not all go into an all-inclusive resort! The only drink offered during the flight was plain water, again a step down from before where they also offered others, e.g. orange juice. Seating - now that big persons have the right for two seats for the price of one, when will the same rational apply to tall people?

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,
