Prime Minister Lawrence Wong breaks ground on Changi Airport T5 on 14 May 2025; all SIA, Scoot flights to move there when it opens

Prime Minister Lawrence Wong has broken ground on Changi Airport Terminal 5 (T5), an expansion project more than a decade in the making that will position the airport to ride an expected surge in air travel within the Asia-Pacific and beyond.
With the May 14 ground-breaking, work on the mega terminal has begun, following delays owing to the Covid-19 pandemic.
National carrier Singapore Airlines (SIA) and its budget arm Scoot will consolidate their operations under one roof at T5 when the terminal opens in the mid-2030s, said operator Changi Airport Group (CAG).
The airlines now operate across Terminals 1, 2 and 3, and SIA Group said the consolidation at T5 will provide space for its future growth and improve “operational synergies”.
There will be room at T5 and other terminals for other carriers to expand their operations, CAG added.
When asked about the other airlines that could operate from T5, CAG said it was too early to tell, as flight operations are dynamic and can change over the next decade.
Designed to handle about 50 million passengers a year, T5 will effectively double the size of Changi Airport and allow it to handle 140 million passengers yearly – boosting its current capacity of 90 million by more than 55 per cent.
Passenger traffic in the Asia-Pacific – already the world’s largest air travel market, taking about a third of the global share – is projected to double in the 2040s.
CAG said the extra capacity at T5 will enable Singapore to take advantage of this growth.
While prize-winning Changi Airport is a source of pride for many Singaporeans, PM Wong said Singapore can never be complacent about its achievements and “cannot presume that our success can continue just on its own”.
Amid sharpening competition from other airports and an uncertain global economy, the Prime Minister said Singapore must continue to work hard and remain connected to the world.
Hence, it is making a “bold move” with T5’s development to ensure Singapore’s air hub stays competitive.
At present, Changi Airport is linked to more than 170 cities. With T5, the airport will be able to reach its target of more than 200 city links by the mid-2030s, said PM Wong.
Construction on T5 will intensify in the next few years and peak around 2029, said Mr Ong Chee Chiau, CAG’s managing director for Changi East.
Works completed so far include a new runway, the airport’s third; an underpass for vehicular traffic; and tunnels for baggage and automated people-mover systems similar to the Skytrain.
With three runways operational by the time T5 opens, a second control tower will be built to manage air traffic, Mr Ong said.
T5 is located within the 1,080ha Changi East development, which is almost as big as the land area of today’s Changi Airport, he added.
In a first for the airport, T5 will house a ground transport centre, bringing together the Thomson-East Coast and Cross Island MRT lines, buses, taxis and other transport services.
State-of-the-art systems
T5 will have overlapping curved roofs with varying heights, in a nod to “Singapore’s unique blend of nature and city”, said CAG.
It will also have natural light and landscaping, giving the terminal “the familiar cosy yet uplifting feel that Changi is known for”.
Besides its facade and interior, the mega terminal will have state-of-the-art systems, and will leverage technology and automation to improve efficiency and passenger experience.
Plans include baggage robots that can operate in poor weather conditions, as well as video analytics and artificial intelligence tools that can track aircraft turnarounds to predict potential delays. A turnaround refers to the time between the arrival of an aircraft and its next departure.
These technologies are being tested now to prepare for their roll-out when T5 opens, said CAG.
To make it easier for passengers to move around, three automated people-mover systems as well as travelators will reduce walking distances.
There will be two people-mover systems within T5 that can connect departing passengers to their gates and arriving passengers to two arrival immigration halls. A third people-mover system will link T5 to T2, facilitating passenger transfers to other terminals.
“Most passengers arriving in Singapore will still be able to hop onto a taxi or the MRT within 30 minutes after leaving the aircraft,” said CAG chief executive Yam Kum Weng.
Meanwhile, transfer passengers at T5 can expect to connect to another flight in less than an hour. “Faster than Changi today,” Mr Yam added.
Passengers departing from T5 will undergo security checks near their boarding gates at the multiple security screening points for each cluster of gates.
This means more flexibility for the airport operator, as it can choose to open or close a particular cluster of gates according to demand, Mr Ong said.
T5 will be powered by more clean energy to reduce the airport’s carbon footprint. Its rooftop solar system – one of Singapore’s largest – will have the potential to generate enough energy to power up to 20,000 four-room Housing Board flats for a year.
It will also be ready to support viable alternative jet fuels, including sustainable aviation fuels.
From 2025, all new light vehicles, forklifts and tractors on the airside will be electric, and T5 will be able to support a fully electric airside fleet, CAG said. The airside is the part of the airport beyond passport control, where aircraft operate.
