Changi Airport Group (CAG) will invest SGD3bn (R40,4bn) over the next six years to upgrade Terminals 1 to 4.
CAG said the investment would help the hub to stay competitive and meet rising demand for air travel before Terminal 5 was operational in the mid-2030s.
Highlights of the planned upgrades include:
-
Skytrain modernisation: Replacement of ageing systems and expansion of car fleets.
-
Baggage handling: Capacity boosts in Terminal 3 and a new rooftop inter-terminal system.
-
Check-in and immigration: Expanded Terminal 4 check-in facilities and larger immigration halls at Terminal 1.
-
Airside upgrades: Reinforced taxiways and additional parking stands for new aircraft like the Boeing B779.
-
Terminal 3 refurbishment: Updated systems and enhanced retail offerings.
To support these investments, passenger fees and airline charges will gradually increase between 2025 and 2030.
Rebates would ease the transition for airlines, while the overall impact on ticket prices was expected to be minimal, said CAG.
