Well it was a 2h delay flight so that said it all. With very little if any information. Boarding took for ever with long waits at the terminal and then in the finger. To top it off and increase the delay we had to take a bus in Zurich. A trip to forget

Swiss is the. Only airline I use when I go to Europe. They are on time and they are fantastic!

The plan was delayed for takeoff by an hour, but we ended up making the landing on time which was a nice surprise.

I can’t even the whole trip was a catastrophe

Delay more than hour created pressure to catch the connecting flight

The food was good. Most the staff was pleasant. The flight would be drastically improved with WiFi on a long international flight.

The crew was very friendly and nice! Very smooth flight.

Each flight we took was late with little or no updates or information.

Clean, efficient and quick response time when we missed our connecting flight.
