Lufthansa arranged for pickup with a van upon disembarking from my late flight from Pisa and took me through a special passport and security checkpoint so that I was able to catch my MUC-SFO flight. Flight departed late, but pilot made up all tge lost time in flight. Crew was professional, very polite and efficient.

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. Also, really tired of the fake business class on these flights...

Flight attendants were great, friendly, courteous and responsive. The relaxation and mediation program was great! Boarding was fluent and easy.

No matter what you try to order on the airplane is totally disgusting. If it's not overloaded with cheese and tomato sauce then it's overcompensated with spices (salt or chili). I will never understand why it is so hard to provide simple, fresh and enjoyable meals. Chairs in economy are rarely cleaned up and one can see on the cushions that they are worn out and have lost their padding making the seats very uncomfortable. There was no foot rest available (which is such a simple addition that helps a lot) and the "holder pocket" on the seat in front was a simple net completely useless. Tables were dirty suggesting they were never cleaned and disinfected. Knowing that the highest source of viruses are the tray tables and the pockets in front I would expect attention to be focused on those- it not only impacts the health of the traveler but more important that of the crew. Why is it so hard to think of this business two fold: make revenue but mostly be kind to humans.

Staff and flight were great. We were surrounded by kind of rude flyers. They complained when my husband moved the seat back. And they were just standing in the aisle most of the time. Person in front of me stretched her arms over the seat so her hands were dangling in front of me and fingers in my screen. I know we were in coach, but maybe another inch of separation would be nice for such long flights.

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!

The plane was new & clean, the pilots executed flawless takeoff & landing, the flight attendants were friendly to a fault, the plane left on time & arrived early.

I was late ( I had to drive 230 Km ) and I managed to call in advance the company that was doing the check-in on behalf of SWISS - I asked them the Check-in time closing time and by almost flying ( speeding like crazy ) I arrived before that moment.

I did not check the terms and conditions of the ticket. I am a Star Alliance Gold member and I was expecting SWISS to have a similar booking system like the others I fly with. I found out that the ticket fare did not contain checked luggage ( so I had to pay a hefty fee for it ) and also my 20" wheeled case that was ok in all the other flights I took it with me, this time was oversized and overweight . My wife took out the 2 laptops so it became within weight limits but still oversized - My wife paid for the fee ( I wasn't there at the time and she is not a such experienced flyier as I am ) . When I found out about the fee, I checked their rules and I found out that the hand luggage is allowed to be 22" . I saw in the airplane a lot of people with cases having the same size as mine, that went as checked luggage at a cost fo around 40 . I want to see how can I get my money back . . .

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.

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.
