Austrian Airlines offers flexible and convenient check-in options, including online and mobile check-in starting 47 hours before scheduled departure for most flights. For flights to or from the United States, online check-in becomes available 24 hours before departure due to regulatory requirements. Passengers can check in via the Austrian Airlines website or mobile app, select seats, enter travel documents, and receive a mobile or printable boarding pass. Online check-in is the fastest way to secure a preferred seat and avoid airport lines. Airport check-in counters generally open about three hours before departure and close 45 minutes before domestic or European flights, and between 60 and 75 minutes before long-haul international departures. At Vienna International Airport, travelers benefit from 24-hour check-in services and dedicated bag drop counters for those who have checked in online. Priority check-in desks are available for Business Class, HON Circle, Senator, and Star Alliance Gold members. Austrian Airlines also provides City Check-In at Wien Mitte station for City Airport Train users, allowing passengers to check in and drop off luggage from 24 hours up to 75 minutes before their flight. Self-service kiosks are available at many airports to assist with printing boarding passes and baggage tags. Austrian Airlines recommends that passengers who are not using online check-in arrive at the airport at least two and a half to three hours before international flights and at least 90 minutes before European departures to allow sufficient time for security and boarding. Check-in deadlines may vary depending on the departure airport and destination, so travelers should verify the specific requirements for their flight. Austrian Airlines also offers automatic check-in for eligible bookings, where boarding passes are sent directly when the check-in window opens. For codeshare flights operated by other airlines, check-in rules follow the policies of the operating carrier. Completing check-in online saves time, improves the travel experience, and helps avoid long queues at the airport. Using Austrian Airlines’ early check-in services ensures passengers are well-prepared for their journey and helps prevent missed flights due to last-minute delays.
