I was pleasantly surprised they had a snack service on such a short flight. The flight attendants were very friendly

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. There were only 2 customs agents!! One for all passports and 1 for all passports. We were in the customs hall longer than we were in flight!

Per usual, KLM can't seem to figure out the order of boarding the plane. Should be business - priority - everyone else. Instead they do priority first, and that's usually two-thirds of the passengers. Strange choice of in-flight movies; no accounting for taste, I guess.

We flew Miami to Zurich, then Zurich to Rome. The international leg was awesome. The intra-European flight was less impressive. We “self-boarded” which was new to us - and wasn’t explained. The seats were smaller and there was only the drop down screens for every 2-3 rows, but otherwise, for a less than 2 hr flight, it was fine.

Boarding wasn’t fully explained for those of us who are not Swiss or German. I slept thru “lunch,” which apparently was a sandwich - but that’s more than many American airlines provide you on similar flights!

I am a frequent flyer with swiss airline. Amazing crew, boarding, taking off and landing is on time if not a little earlier. However, I was quite disappointed with the enertainment package and food.

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.
