Mediocre 3.3

Cons: 12 hour flight with no in flight movies unless you paid an extra EUR 10. Food tastes bad, plus I was skipped from the second meal despite having prepaid for it (flight attendant overlooked that my seat was on a list, part of the problems that come with nickeling and diming for every single thing including even meals on an international flight). Despite flying to the US, attendants consistently only spoke German to me and my wife, did not speak on both German and English.

Cons: No food or drink is included in the price, narrow seats, delayed flight. We were already seated when it turned out the departure will be delayed by 30 mins. No toilet use during this time....

Prices are per person, are for e–tickets and include all taxes & fees in GBP.

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 prices, so it’s not possible for us to guarantee what other companies are selling.

We aggregate tons 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 don't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car hires 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.

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.
