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.

Excellent 8.0

Cons: Service desk personnel at the gate were very helpful and attentive. The plane was only 1/2-2/3 full, which made boarding quicker. The food was tasty and coffee was great! We were also offered juice twice during the flight. Bathrooms were clean. Since the plane wasn't full, they weren't dirty even at the end of the flight. I brought my own headphones, but the stewards provided them if you need them. My one big complaint was that our seats did not recline, thus making any kind of shut-eye near impossible. Our plane left and hour late, but the pilots stepped on the gas and we got in on 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
