Online check-in is available via the Singapore Airlines website and mobile app using your booking reference. Check-in opens 48 hours before departure on most routes, or 24 hours before for US-bound flights. It closes 1.5 hours before departure on the website, or 1 hour before via the mobile app. Check-in is free, and a digital boarding pass is issued immediately.

Steps:

  1. Visit www.singaporeair.com or open the Singapore Airlines mobile app
  2. Enter your booking reference and passenger surname
  3. Review flight details and passenger information
  4. Select your seat (if not already assigned)
  5. Accept baggage declaration and receive your digital boarding pass
  6. If you have checked baggage, proceed to the bag drop counter at the airport after online check-in

Tip: Use the mobile app for earlier check-in closure (1 hour vs. 1.5 hours), giving you more flexibility on the day of travel.

Can I check in at the airport if I miss online check-in?
Yes. You can check in at the airport counter, but arrive early to allow time for bag drop and security screening. Online check-in is recommended to save time.
What if I need to change my seat after online check-in?
You can modify your seat selection on the website or app until check-in closes. At the airport, ask the bag drop agent to assist with seat changes if needed.
