good service in spite of rather crammed conditions and short flight, UK newspaper was available, plenty of leg room (biz class consisting of one row in the front:))) - the lucky 4 in that 1st row were the only ones to get food, and also drink for free, it seems... and yes, the flight was short and otherwise uneventful, I was the 1st to walk off the plane.

The plane was a tiny oldish commuter jet with 2 seats on each side of the aisle. In "biz class" you still had to rub elbows with your neighbor, something other airlines with newer planes have sorted out, but allowing extra space between seats.... but overall, for a short flight (not much longer than an average subway commute in NYC), it really was not a huge deal....

Lounge is nice, if busy. Finnair staff offered me a better seat at check in. Seats flatten out and have many features. Tons of convenient items all marimekko - nice pillows, blankets and slippers. Helpful and attentive staff, always check on you but also give you plenty of time to snooze. Nice skin products and omg, clean bathroom. Easy to relax.

The Asian vegetarian meal is rice and chickpeas! Was not too bad but also my breakfast was more chickpeas and grilled zucchini. I never requested a "vegetarian breakfast" - feel bad wasting food like this. I sent the veg salad back opted for fruit salad croissant.

I didn't like that seats originally assigned after the flight was booked were changed right before the boarding. This is a nonsense. Why would you do that?! Without notifying prior to check-in.

Amsterdam customs is the most disorganized I have ever seen. With the number of tourists entering the country you would think they would have done something about it.

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,
