Yes, you can absolutely buy a Swiss Travel Pass at Zurich Airport (ZRH) upon arrival in 2026. After you clear customs and enter the "Airport Center," look for the SBB (Swiss Federal Railways) Travel Center, which is located one level below the arrivals hall, right next to the entrance to the train platforms. The office is typically open from 6:15 AM to 10:30 PM daily. While you can buy the pass at the counter using cash (CHF, EUR, USD) or credit cards, there are a few reasons to consider buying it online instead. An online "E-Ticket" allows you to skip the potentially long lines at the ticket office and proceed directly to your first train. However, the airport staff are incredibly helpful and can provide you with physical maps and advice on your itinerary that you won't get from a website. The price is identical whether you buy it online or at the airport station. If the main ticket office is crowded, there are also SBB "Ticket Machines" nearby that sell shorter-duration passes, but for the multi-day Swiss Travel Pass, the staffed desk or the official SBB mobile app are your best bets for a smooth transaction.
