Again, no aisle seat for SkyTeam Gold member. Also, my baggage was lost. First bag arrived a day late, second after I had left Billund and it was six days before the bag with my clothes reached me. I was told I will have 100 euro credit for clothing, but in the winter and for 6 days, this was not even close to the amount I needed for clothing and necessities, to have my time here.

Pretty basic one hour flight so there's not much to complain about or praise about. I got some sleep which was good.

The crew had their general Dutch aloofness on form. Chatted to one of the stewardesses in Dutch up until she saw I had a British passport then she decided she could only speak English to me.

After 5 mins, I pushed the service button and nobody responded. After half hour, I ordered the food from another crew passed by. After I landed, they suppose to return my stroller set at the airplane gate. But they said it is not there, ask us to wait at the airport gate. We walked outside and they broadcasted again, I didn't hear very clearly but followed most parents to walk out. We wait at the baggage claim for almost 1 hour and finally, the baggage crew came back to the gate and found our stroller.

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,
