The worst airline I have ever dealt with!
My flight was delayed and I ended up having to stay in Heathrow for the night. The airline said they were unable to book me a hotel but to book one myself and they would reimburse me. Literally 18months on I am still trying to get my money back from this. The customer service is horrific and the airline has been so underhanded this whole time. Initially claiming they couldn't pay me out the full amount as the hotel exceeded their budget (of $200??, where can you find a last minute airport hotel for $200??) When I finally gave up and accepted that was all I would be getting they decided to pretend they had already paid me and claimed it had already been sent to my account. When I had bank statements showing I had never received it they just stopped replying. I have never dealt with such a petty and underhanded company.

Where do I start?! On check in staff very rude and insisting that hand luggage checked in, despite having a disabled partner that had medication in the hand luggage.
On the journey staff are quite rude and
Then delayed flight with a connection in Zurich, staff say no problem, but got to gate for connecting flight (several other travellers too) and gate closed with no sign of staff anywhere. Airport staff indicated to go to other terminal, queue through passport control to enter EU (one passenger wasn't accepted) and then queue to see what they can do. Have to take a flight to Munich, wait 5 hours then another flight to Manchester, in total arrived 10 hours late.
Finally, no hold luggage arrived, had to wait to make a luggage claim (luggage desk saying Swiss worse airline). Luggage did eventually get traced, say it will arrive the following day (cant even contact them) and eventually arrives 2 days later.
Ask their customer services and response is 'outside of EU regulation so we won't do anything'
Worse experience I've ever had and I've been fortunate enough to do lots of long haul.

Flight was cancelled but Swiss refused any compensations according to the EU rules 261/2004 due to bad wind conditions. All other flights are done, no cancellations and we flight with AUA 4 hours later without any problems

First flight they miss my luggage and on the way they delay ans miss my connection flight . Worst airline and stupid operation.

Lack of manners trying to force you to check your luggage in the hold instead of letting you bord It. Let's hope they don't loose It or damage It.
Apart from that, the flight was delayed.

Will avoid this airline in the future.
