Zurich Airport cleared 3 million passengers in May, handling 3,028,701 travellers, up 9.1% year on year.
The month combined 2,222,403 local passengers and 801,998 transfer passengers, with the transfer share at 26.5%. Traffic also improved across the operating profile: movements rose 5.1% to 25,318, seat load factor reached 79.7%, and freight edged up 1.2% to 37,369 tonnes. Average passengers per movement climbed to 134.3, showing that capacity growth is still being absorbed efficiently rather than forcing a sharp increase in rotations.
The pattern points to a hub that is still expanding on volume while preserving strong utilisation. For operators, the next test is whether this demand holds through the summer peak without eroding punctuality or slot productivity.
