Singapore Airlines is known for its smooth airport experience and premium service standards. Still, travelers must follow the official Singapore Airlines check-in policy to avoid last-minute stress, missed deadlines, or boarding issues. Whether we check in online, through the mobile app, or directly at the airport counter, understanding check-in timing, baggage drop procedures, and document requirements ensures a seamless journey.

This guide explains everything we need to know about Singapore Airlines check-in, including deadlines, check-in methods, baggage rules, and important tips for international travel.

Singapore Airlines Check-In Options

Singapore Airlines provides several convenient check-in methods, allowing us to choose the most suitable option based on our route, travel needs, and airport facilities. The main check-in options include:

• Online check-in
  
  

• Mobile app check-in
  
  

• Airport counter check-in
  
  

• Self-service kiosk check-in (available at select airports)
  
  

• Early check-in services (only at certain locations)
  
  

Each option works efficiently, but travelers must always follow strict check-in closing times.

Singapore Airlines Online Check-In Policy

The Singapore Airlines online check-in process is one of the fastest ways to secure a boarding pass and reduce airport waiting time.

Online Check-In Time

Online check-in generally opens:

• 48 hours before departure
  
  

And closes:

• 1.5 hours before departure (for most flights)
  
  

Once checked in, we can download or print the boarding pass and proceed directly to baggage drop if we have checked luggage.

What We Can Do During Online Check-In

Online check-in typically allows us to:

• Confirm passenger and flight details
  
  

• Choose or adjust seating (based on fare conditions)
  
  

• Access a digital boarding pass
  
  

• Add frequent flyer details
  
  

• Review baggage allowance
  
  

Online check-in is ideal for travelers with carry-on baggage only or those who want faster airport processing.

Singapore Airlines Mobile Check-In Policy

Singapore Airlines also supports mobile check-in through its official mobile app. Mobile check-in follows the same time window as online check-in and offers a digital boarding pass that can be stored on a phone.

Mobile Check-In Benefits

Mobile check-in helps us:

• Avoid printing paperwork
  
  

• Keep travel details accessible
  
  

• Move faster through airport processes
  
  

• Reduce time spent at check-in counters
  
  

Singapore Airlines Airport Check-In Policy

For travelers who prefer traditional service, Singapore Airlines offers airport check-in through staffed counters.

Recommended Airport Arrival Time

To ensure enough time for baggage drop, immigration, and security, we should arrive:

• 3 hours before international flights
  
  

• 2 hours before shorter regional flights (depending on airport size)
  
  

Airport check-in is strongly recommended for travelers who require document checks, visa verification, or special assistance.

Singapore Airlines Check-In Deadlines (Important Rules)

Singapore Airlines enforces strict check-in deadlines. Missing the check-in cutoff may result in denied boarding or ticket changes.

Standard Check-In Closing Time

In most airports, Singapore Airlines check-in closes:

• 60 minutes before departure
  
  

However, some airports may require passengers to complete check-in 75 to 90 minutes before departure, depending on local airport rules.

Boarding Gate Closing Time

Even after check-in, we must reach the gate early. Boarding gates may close:

• 15 to 20 minutes before departure
  
  

Arriving late at the gate can still result in missed boarding, even if check-in was completed.

Singapore Airlines Self-Service Kiosk Check-In

At select airports, Singapore Airlines provides self-service kiosks that allow us to:

• Check in quickly
  
  

• Print boarding passes
  
  

• Print baggage tags
  
  

• Proceed to bag drop
  
  

Self-service kiosks are useful during peak travel hours when check-in counters have long queues.

Singapore Airlines Baggage Drop Policy After Online Check-In

Even after completing online check-in, passengers with luggage must drop bags at the airport.

How Bag Drop Works

After online or mobile check-in, we must:

1. Go to the Singapore Airlines bag drop counter
   
   

2. Submit checked baggage
   
   

3. Collect baggage receipts
   
   

4. Proceed to security and immigration
   
   

Bag Drop Closing Time

Bag drop counters typically close:

• 60 minutes before departure
  
  

We should always reach baggage drop at least 90 minutes before departure to avoid delays.

Singapore Airlines Checked Baggage Allowance Overview

Singapore Airlines baggage allowance depends on several factors, including:

• Cabin class
  
  

• Fare type
  
  

• Route rules
  
  

• KrisFlyer membership level
  
  

Singapore Airlines generally applies two baggage systems:

• Weight concept (common across many international routes)
  
  

• Piece concept (often used for travel to/from the USA and Canada)
  
  

Premium cabins such as Business Class and First Class typically include higher baggage allowances.

Singapore Airlines Carry-On (Cabin Baggage) Policy

Singapore Airlines enforces clear cabin baggage rules to maintain comfort and safety onboard.

Most passengers are allowed:

• One main cabin bag
  
  

• One personal item (such as a laptop bag or handbag)
  
  

Cabin baggage weight and size limits may vary depending on cabin class and route, so checking the latest allowance before travel is always recommended.

Singapore Airlines Check-In Policy for International Flights

International flights require additional planning because travelers must meet passport and entry requirements.

Even if we check in online, Singapore Airlines may require:

• Passport verification at the airport
  
  

• Visa validation for restricted destinations
  
  

• Document checks for transit routes
  
  

To avoid delays, we should keep all travel documents accessible and ensure the passport matches the booking details.

Singapore Airlines Check-In for Codeshare Flights

For codeshare flights, check-in procedures may differ because the operating airline may manage the airport process. In these cases:

• The operating airline may control check-in counters
  
  

• Baggage rules may vary
  
  

• Airport signage may show the partner airline name
  
  

We should confirm flight operating details before arriving at the airport.
