Cons: It would have been better if the ticket I purchased was the one that I selected. It was not as advertised. I searched for ticket that was translatlantic with one checked bag. BUT kayak booked an ECONOMY LIGHT fare that required payment. It was not as advertised and a total head ache for check in.

Cons: Be like Swiss or Lufthansa. Charge less and give free water and snacks

Okay 4.0

Pros: This flight was eventually cancelled and the rating is solely on the ground experience. EuroWings could not have done anything worse. The process took from 10:30am upon arrival in Dusseldorf til 11:00pm when we were told the counter closed at 10pm and nothing could be done till next day.

Cons: Have representatives on the ground and make public announcements about the progress, next steps, help offered and steps that need to be taken. The info was sparse and had to be gotten on an individual basis. Nothing was coordinated or communicated and every step had to be done WITHOUT HELP.

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.
