How to get from Terminal 1 to Terminal 3 in Singapore Changi Airport?

Moving between Terminal 1 (T1) and Terminal 3 (T3) at Singapore Changi Airport is surprisingly simple, as the terminals are physically connected within the same complex. Whether you are a transit passenger or just exploring, you can use the Skytrain, walk through airside travellators, or take a shuttle bus during late-night hours. The route you take depends largely on whether you have already cleared immigration or are still in the public area.

In my experience navigating Changi, the Skytrain is almost always the best bet for speed. However, there is one counterintuitive factor that 90% of travelers overlook when they are in a rush - I will explain exactly why the walking route might actually save your connection in the walking section below. Usually, a transfer between T1 and T3 takes about 30-45 minutes total, accounting for walking to the gates, which is why Changi is consistently ranked among the top airports globally for efficiency.

Airside Transfer: For Transit Passengers

If you are in transit, you do not need to clear immigration to move between T1 and T3. Changi’s transit area is a continuous loop. Follow the prominent Transfer signs to navigate between terminals. This airside connectivity is a lifesaver for those with tight connections, as it eliminates the need for repeated security checks in most cases.

Option 1: The Skytrain (Recommended)

The Skytrain is the fastest way to bridge the gap. In T1, head to Station C; this train will take you directly to Station B in T3. The ride itself takes approximately 4 minutes, and trains arrive every 1 to 4 minutes. The system operates from 5:00 AM to 2:00 AM daily. It is smooth, air-conditioned, and offers a great view of the airport’s lush greenery.

I remember the first time I used the Skytrain - I was frantically looking for a ticket machine. Plot twist: it is completely free. You just walk on. But here is the thing: if you are carrying very heavy luggage that is not on a trolley, the walk to the Skytrain station from the far ends of T1 can feel like a marathon. The Skytrain is popular among transit passengers, but it is not the only way.

Option 2: Walking via Travellators

If you prefer to stretch your legs, you can walk between T1 and T3. The transit areas are connected by long corridors equipped with travellators (moving walkways). This walk typically takes 15-20 minutes. It is a great way to see the various gardens and shops that make Changi unique. You will find T3 and T1 meet near the junction of Terminal 2.

Remember the critical factor I mentioned earlier? Here it is: the Skytrain stations are centrally located.

If your arrival gate in T1 is at the far end and your departure in T3 is also at a far wing, the changi airport skytrain t1 to t3 route might actually take longer because of the backtracking required to reach the stations.

In this specific scenario - and I have tested this during a short layover - walking the long way via the travellators is often faster because you are moving in a direct line toward your gate. Sometimes the automated solution is not the smartest one.

Public Area Transfer: Before Immigration

If you are in the public area - perhaps you just landed and want to visit the Jewel before checking in at T3 - your options change slightly. You can still use the Skytrain on the public side, but many people find the walk through Jewel Changi Airport much more scenic.

From T1, follow the signs toward Jewel. You will walk across a link bridge that leads directly into the heart of the mall. From there, another link bridge connects Jewel to T3. It is about a 10-minute walk in total. I once tried to do this with three huge suitcases and no trolley. Bad idea. My arms were aching by the time I reached the T3 check-in counters. Always grab a trolley; they are free and plentiful.

Transferring During Late Night Hours

The Skytrain shuts down for maintenance between 2:00 AM and 5:00 AM. If you find yourself in Changi during these early hours, do not panic. The airport provides a transit shuttle bus service that mirrors the Skytrain route. Look for the Shuttle Bus to T3 signs in the transit area of T1. These buses run every 15 minutes and ensure that no traveler is stranded, even in the middle of the night.

T1 to T3 Transfer Comparison

• Under 4 minutes (train ride only)

• Low - best for passengers with children or light bags

• 5:00 AM to 2:00 AM

Walking (Airside)

• 15 to 20 minutes

• Moderate - great for gate-to-gate directness

• 24 hours

Shuttle Bus

• 8 to 12 minutes

• Low - essential during Skytrain maintenance

• 2:00 AM to 5:00 AM

The 55-Minute Connection Sprint

David, a consultant traveling from London to Sydney, landed at T1 with exactly 55 minutes to catch his T3 connection. He was exhausted and worried because his first flight was delayed by 20 minutes, leaving him with a razor-thin margin.

He initially ran toward the Skytrain station, but seeing a large queue of travelers, he realized he might miss the next two trains. He felt a surge of panic as the clock ticked down and he stood frozen at the platform entrance.

He suddenly remembered a tip about gate-to-gate walking and checked the map. His arrival gate was D34 and departure was B2. He realized they were actually closer via the walking path than the train stations.

David reached his gate in T3 with 10 minutes to spare before boarding closed. He learned that during peak hours, skipping the 'fast' train for a steady walk can be the difference between making a flight and spending the night in the terminal.
