How Many Hours Before Check-In Singapore Airlines?
Singapore Airlines allows online check-in 48 hours before scheduled departure, closing 1.5 hours (90 minutes) before the flight. You can check in through the Singapore Airlines website or SingaporeAir mobile app by entering your booking reference and last name. During online check-in, you can choose your seat, enter passport and visa details, pay for baggage, and download or email your boarding pass. If you’re traveling with hand-carry only, you can proceed directly to airport security upon arrival. If you have checked baggage, drop it at the airport's baggage drop counter before the deadline. For airport check-in, counters usually open 3 hours before international flights and 2 hours before regional or short-haul flights. Airport check-in counters typically close 40 to 60 minutes before departure, depending on your airport and destination. It is recommended that passengers arrive at the airport at least 2 to 3 hours before flight time, regardless of check-in method, to allow for baggage drop, immigration, and security screening.
Singapore Airlines also offers self-check-in kiosks at major airports, including Singapore Changi Airport. These kiosks open at the same time as the airport counters and allow passengers to check in, print boarding passes, and print baggage tags. After tagging your luggage, you can proceed to the baggage drop counter. This option reduces wait times and streamlines the check-in process for those not using online check-in. At Changi Airport, automated bag drops and immigration e-gates make the process faster. However, passengers must still arrive early to complete all steps before boarding. Boarding usually starts 40 to 50 minutes before departure and gates close 10 minutes prior. Singapore Airlines does not hold flights for late passengers, even if you are already checked in.
For flights involving document checks—such as those requiring visas, vaccination proof, or health declarations—online check-in may be limited, and in-person check-in will be required at the airport. Always review the entry and document requirements for your destination before traveling. If you’re flying on a codeshare flight operated by a partner airline, check-in policies may differ, and you should refer to that airline’s check-in rules.
Singapore Airlines recommends completing check-in as early as possible, especially during peak travel periods, weekends, or holidays. Early check-in ensures preferred seat selection, faster airport processing, and fewer delays. Digital boarding passes via the SingaporeAir app also help speed up gate access and reduce paper use.
In summary, Singapore Airlines check-in opens 48 hours before departure online and closes 90 minutes before takeoff. Airport check-in starts 2 to 3 hours before departure and closes about 40 to 60 minutes prior. Arrive early, check in online or at a kiosk, and complete all procedures on time to enjoy a smooth journey with Singapore Airlines.
