I found Zurich airport to be very customer service friendly. Plenty of signage to guide travelers to their destination( whether it was gates or security or baggage claim, shopping mall) etc.
Plenty of restaurants and souvenir stores. There were also hundreds of specialty shops and then a grocery store also. There were numerous service desks for trains, flights and other travel needs.
All these shops were right across the terminal building which one can just walk across. There was the major train station underneath to take various trains across the network.
The layout was very simple. One floor to check in all the airlines. Just find out zone. Then security check point, followed by train to departure level and customs. read more
