One of the world's busiest airports reveals plans for new £7 billion mega terminal for 50 million more passengers

One of the busiest airports in the world is set to be transformed with a brand new terminal that will handle millions more passengers.

The airport is already known for being home to the world's biggest indoor waterfalls and has previously been voted the best in the globe.

Now Changi Airport in Singapore has unveiled plans to build Terminal 5, which is set to add an incredible 50 million more passengers to the already 90 million that pass through yearly.

T5 will also be connected to the existing Terminal 2, which is home to Singapore Airlines.

When completed, the terminal will bring the airport's connectivity from 170 to 200 cities worldwide.

Plans released by the airport show the impressive infrastructure planned for the terminal building, which is expected to cost £7billion.

It will have huge glass roofs and walls to allow as much natural daylight as possible to flood the mega terminal, creating a better transit for passengers.

Just like Changi Airport's existing terminals, no expense will be spared on facilities and scenery, with indoor gardens and vertical trees planned throughout the building.

Automated check-in desks and contactless touch points will be introduced, allowing for a faster and more seamless experience for departing and arriving passengers.

A dedicated transportation centre will also be constructed underneath the terminal, which will house trains, buses and taxis.

Work has already started on the 2,670 acre site and, when it opens, the airport's size will have almost doubled.

To allow for the additional passengers, airport bosses will convert a former military runway into a third runway to be used for commercial aircraft.

The terminal is expected to be fully operational by the mid 2030s, but the third runway could be open by 2027.

Meanwhile, Dubai's busiest airport previously revealed plans to shut down as it undergoes a £28 billion expansion to increase its capacity to 260 million passengers annually.

Dubai International Airport, known as DXB, is a major travel hub and a key destination for long-haul travel for millions of Brits who flock to the Gulf city each year.

But its boss, Paul Griffiths, announced all services will eventually be moved in the coming decades to the newer Al Maktoum International Airport (DWC).

Located 22 miles outside of the city and 38 miles from DXB, Al Maktoum International Airport opened its doors in 2010, though a new DWC terminal is expected to open in 2032 and full expansion will continue into the 2050s.

According to Griffiths, Dubai International Airport, which first opened in 1960, is nearing the end of its 'useful operating role'.

Speaking at the Arabian Travel Market conference last month, he said: 'There is little sense in operating two major hubs with such close proximity to one another.

'We will move every single service to DWC. By then, every single asset at DXB will be close to the end of its useful operating role, so the economics of keeping DXB open will not be possible unless we invest a huge amount of money.'

DXB is currently the world's second busiest airport, having handled a record 92.3 million passengers in 2024, but it holds the top spot as the world's busiest for international passengers, as reported by Aviation Week.
