The rating is from results of passenger surveys from more than 280 airports worldwide, and is part of ACI's Airport Service Quality awards.
At least 1,400 passengers at each participating airport were questioned on a variety of services using a standardised questionnaire. In the Europe category, Zurich Airport was placed second behind Moscow Sheremetyevo. In the category of airports with between 15 and 25 million passengers, Zurich came in fifth place worldwide, behind Seoul Gimpo, Chongqing, Tampa and Salt Lake City.
"This award is well-earned recognition for all the employees who contribute towards smooth operations and outstanding quality at Zurich Airport," said Thomas Kern, chief executive of Flughafen Zürich AG.
