At Zurich Airport (ZRH), Swiss International Air Lines (SWISS) utilizes Terminal A and Terminal E, with Check-in 1 and Check-in 3 serving as their primary passenger hubs. Terminal A is the dedicated base for SWISS domestic flights and those within the Schengen Area, while Terminal E is a satellite terminal specifically designed for non-Schengen and long-haul international departures. Check-in 1, located in the main landside building, is where most SWISS passengers drop their bags, though the high-tech Check-in 3 above the railway station is also a major hub for the airline's self-service bag drops. Because SWISS is the flag carrier of Switzerland, its presence at ZRH is extensive; the airline operates nearly a dozen world-class lounges across these terminals, including the famous Senator and Business lounges that feature alpine-inspired wood and stone designs. For passengers, the integration between these terminals is seamless, with the "Skymetro" automated train connecting the main terminal building to the gates in Terminal E in under three minutes, complete with authentic Swiss cowbell sounds.
