📱 Different Ways to Check In: Online and On-Site

Streamlining Your Journey at Changi Airport

Singapore Changi Airport offers the FAST (Fast And Seamless Travel) system — a collection of self-service options designed to speed up your entire departure process. With FAST, eligible passengers can print boarding passes and bag tags at automated kiosks, drop off checked bags using automated bag-drop machines, clear immigration via biometric-enabled gates, and finally board their flights with ease.

Automated Boarding Gates (ABGs) are part of this streamlined experience but focus specifically on boarding. Located mainly at Terminal 4, ABGs allow passengers who’ve cleared immigration recently to board quickly using facial recognition and boarding pass scanning.

Online Check-In

Most airlines flying out of Singapore offer online check-in starting 48 hours up to 1.5 hours before your flight’s departure. By checking in online, you can select your seat and get your electronic boarding pass in advance, saving time at the airport and allowing you to skip long queues.

Airport Counter Check-In

For flights departing from Singapore Changi Airport, counter check-in typically closes 60 minutes before departure. However, some airlines may require earlier check-in for international flights. For example, flights to the US may need you to check in earlier, so it's always a good idea to check with your airline for specific requirements.

Airport Self-Check-In & Baggage Drop

Self-check-in kiosks at Changi Airport close around 60 minutes before the flight’s departure. If you have checked baggage, it’s recommended to arrive at least 2 hours before your flight to ensure enough time for baggage drop and security checks, ensuring you’re not rushing before boarding.
