Excellent outstation service, very friendly crew, IFE is better than in Lufthansa but the seat is bit less welcoming. They have a door of sorts, if you have social issues.
Arrival service in ZRH was a bit expeditive and maybe not up to what you should expect in first class-
Arrival terminal is a great thing... even if they don't stack the "Reportagen" Magazine anymore...

My return flight from Bangkok is with them unfortunately, booked via Austrian airlines. never had problems with Austrian, but they didn't have suitable return flights, and so they offered Swiss.
It took multiple attempts to reach Swiss, and finally they denied my request to bring back my cat with me. So, I have Austrian who let me take my cat to Bangkok and then Swiss told me that I can leave my cat there :-D Why? Because "quota is exceeded" Quota on my leg space under a front seat? I actually not sure :-D I wrote to them in English, they replied in German... Never again with them, now have to reschedule everything.

Yesterday I had a flight from Berlin to Barcelona with a stopover in Zurich, the first flight was delayed for 1 hour and a half and we missed the second flight to Barcelona. I arrived in Barcelona at 12 pm when I should have arrived at 7 pm. Because of this delay I had to spend the night in Barcelona because I'm not from there, missing a train to Zaragoza (my city) and spending 100 euros on a taxi (at that time there were no trains or buses) and missing my train having to buy other tickets for the next day. I was lucky that in Barcelona I have family with whom I was able to spend the night there. This 5 hour delay has caused me to lose 100 euros apart from my time without any compensation. This company does not have customer service for these cases or telephone numbers or emails in its own country and when trying to request this compensation for its website or its application it gives errors and does not stop because of its fault. If someone from the company can help me to give me the corresponding compensation that would be great and for those of you who are not from the company, think about it before traveling on it.

Terrible service.
I join the quire and would have given a zero.
Will never fly again.
Swissair cancelled our return flight, but I have had to contact them 3 times to have a refund. Still not received nearly two months after the cancellation.
Must be illegal and should be prosecuted.

Our baggage did not arrive with our flight. We got an email asking for address to deliver the baggage which arrived in a later flight. We waited all day with no update so decided to go back to the airport. After making multiple calls and asking around we finally found a counter where we were guided to our luggage. A day meant for tourism wasted in tracking our luggage. Never flying Swiss again
