Singapore is an excellent hub for regional travel all over Asia. International flights often transit through Singapore, and travellers often have layovers varying from a few hours to occasionally overnight at the airport. Some travellers use Singapore as an initial “landing-base” in Asia and then fly out using one of the smaller regional airlines like AirAsia, JetStar, Scoot etc. In these cases, many traveller wisely opt to stay a night in Singapore to minimize the risk that their long-haul flight does not land in time for them to take their outbound flights elsewhere. You may not want to go through the cost and hassle of booking a hotel in the city if your plan is just to fly out again the next day. This blog post will highlight your options of how to manage an overnight layover at Singapore Airport; what to expect, where to sleep and discuss some practical tips on how to make your Changi stay as smooth and comfortable as possible.
Singapore Airport is a destination in itself; offering lush indoor gardens, world-class dining and shopping, a free movie theatre, spas, and quiet rest zones that make a long transit genuinely enjoyable. Most terminal are seamlessly connected by a convenient airside train that runs 24 hours, and for longer layovers, there are transit hotels, lounges, and even nature trails, art installations, and an impressive man-made waterfall. It’s easy to relax, recharge, or explore without ever leaving the airport. Many travellers plan extended layovers at Changi simply because it turns waiting time into part of the journey.

What to Expect During an Overnight Layover at Changi Airport
Changi Airport has 4 terminals that operate 24 hours a day. Terminals 1, 2 and 3 are all connected and have an airside train for you to move between terminals. Terminal 4 is a satellite terminal that can only be reached by a free shuttle bus that also runs every 10-20 minutes, 24 hours a day.
Terminals 1, 2, and 3 at Singapore Changi Airport are directly connected to the Jewel Changi Airport – an impressive glass and steel architectural wonder resembling a gemstone that is a land side public space. Terminals 1-3 are connected to the Jewel via covered walkways, making it easy for travelers to move between flights and one of the airport’s standout attractions. The Jewel features the iconic HSBC Rain Vortex – the world’s largest indoor waterfall, lush indoor gardens, a wide range of dining and shopping options, walking trails, and relaxing spaces that feel more like a nature retreat than a mall. For passengers with time between flights, it’s an effortless way to stretch your legs, enjoy a proper meal, or simply experience one of the world’s most unique airport spaces.
Terminal 1, 2 and 3 services most long-haul and large carrier flights, while Terminal 4 generally services shorter flights with low-cost carriers. It is important to remember the distinction about Terminal 4 being basically a distinct terminal from Terminals 1-3 as booking a flight out of terminal 4 on an overnight layover will change your experience dramatically as you will not be able to access Terminals 1-3, once you are airside in Terminal 4. Traveller flying out of Terminal 4 can still visit the Jewel Changi, but they should do so before they go through customs and security at Terminal 4. So keep this in mind as you’re making your travel plans.
If your in-bound flight lands in Terminals 1, 2, or 3 and your out-going flight – whether it is on a separate or connected ticket – you’ll be able to access all three terminals by either staying in-terminal after your flight arrives in Singapore (in the case that your outgoing flight is on the same ticket as your inbound flight); or in the case that your outgoing flight is on an separate ticket, you’ll need to cross customs first and then re-check in for your outgoing flight (assuming you’re flying to a different country).
If your inbound and outbound flights are on the same ticket, you generally won’t need to worry about retrieving any checked bags (unless your airline advises you to do so), so you’re free to wander the wonders of Changyi Airport’s terminal 1- 3 as soon as you arrive.
If your inbound and out-bound flights are not on the same ticket you may need to go through customs first and re-check in for your next flight. If you’re not flying with checked bags, you can actually check in to your out-going flight up to 24 hours before it leaves to enjoy the many amenities of the airport before your flight.
If you do have checked bags, there is actually an early check-in program that allows you to check your bags in 12 – 24 hours prior to your flight so you can also enter the airport early to enjoy its amenities. The program is only available for certain carriers so do review to see if it may apply to your flight https://www.changiairport.com/en/fly/departure-guide/early-check-in-services.html. The easiest is to forgo checked bags if you’re planning to have a long layover at Changi as many amenities like the free sleep areas and transit lounges are airside, and having checked bags often keeps you landside until 3 hours prior to check-in before you can get through security.
Sleeping at Changi Airport
There are a two major options for sleeping at Changi airport. One would be to book room at the one of the three land-side hotels that are directly connected to the airport via covered walkways. The YOTELAIR Hotel is located inside the Jewel which is connected to terminals 1-3 via walkways and to terminal 4 by the shuttlebus + walkways. The Crowne Plaza Changi Hotel is located landside in Terminal 3, and the Changi Transit Hotel is located airside in Terminal 3. The Aerotel Singapore is the only in-terminal hotel in the world that has a full pool, spa and gym. It is located landside in Terminal 1.
Another option is just to sleep in the airport itself. This is much easier done airside than landside, as each terminal actually has complimentary designated sleep areas airside that are furnished with lounge beds for you to actually have a comfortable rest – there is no such amenity landside – unless you book one of the landside hotels. This is where it becomes much easier if you only travel with carry-on baggage, as there’s no need to wait for the 3 hour window before your flight leaves to enter the secure area – so long as you have downloaded your boarding pass electronically. There’s also the Changi Early Check-in program mentioned earlier, but that only works with specific carriers.
Note that even though you need to pass both customs and security to get airside, you may still be woken up by the airport police airside to check your passport and boarding pass. Aside from the occasional police inspections, sleeping airside in one of the sleep zones is a very pleasant experience – and it’s also completely free!
The Ambassador Transit Lounge in Terminal 2 and in Terminal 3 – both airside – also have nap rooms where you can pay in blocks of hours corresponding to your layover or desired rest time. Both these lounges also have lounge packages that can include food, showers, and even the use of a gym!
If you’re not able to get airside. My strong recommendation is to get a hotel. Given how stringent security was sleeping in public areas airside – I can only imagine how things would be landside.
Useful Information for Sleeping in the Airport
If you decide to sleep in the airport here are some helpful information that can help you better plan your night. Note this information is for those staying airside. There are not many amenities available for those staying landside which is another reason why I recommend staying at a hotel if you can’t get airside.
- Food: A limited selection of eateries and convenience stores stay open 24 hours.
- Showers: Available in select lounges and paid facilities.
- Wi-Fi and charging: Free Wi-Fi is available throughout the airport, with plentiful charging points.
