Changi Airport Group (CAG) has announced a significant investment of S$3 billion over the next six years aimed at enhancing services and infrastructure at Singapore Changi Airport, specifically across Terminals 1 to 4.
This initiative is set to improve passenger experiences through various upgrades, including advancements in baggage handling, check-in processes, immigration procedures, and Skytrain connections, while also replacing outdated systems. These enhancements are crucial for maintaining the airport’s competitiveness and preparing for the expected increase in air travel leading up to the opening of Terminal 5 in the mid-2030s.
The investment is not only focused on improving passenger experiences but also looks to boost airport capacity and operational efficiency. To support these upgrades, airport charges will gradually rise between 2025 and 2030. This necessary adjustment aims to finance improvements while managing increasing operational costs.
Recognising the potential challenges these changes may bring to airlines, CAG will implement a 50% rebate on increases in landing, parking, and aerobridge charges during the initial six months. This rebate is designed to help airlines adapt to the new financial landscape.
Furthermore, the anticipated increase in passenger fees is expected to be minimal, estimated at around 1% or less of an economy class ticket for many flights. This means that travellers can continue to enjoy the high-quality services at Changi Airport without facing significant financial burdens due to price hikes.
CAG’s S$3 billion investment will focus on several key enhancements:
Skytrain System Revamp: Updating subsystems, including signalling and communication, along with new cars for added capacity.
Baggage Handling Upgrades: Enhancing Terminal 3’s baggage handling system and establishing a new inter-terminal baggage conveyance system between Terminals 1 and 3.
Increased Check-In Capacity: Adding new check-in rows at Terminal 4 to improve capacity by approximately 15%.
Expanded Immigration Halls: Increasing capacity in Terminal 1's Immigration Halls by nearly 60% to streamline processes.
Strengthened Airside Infrastructure: Upgrading facilities to accommodate new aircraft types, including Boeing’s B779 family expected in 2026.
New Airside Facilities: Increasing remote parking stands for both passenger and cargo aircraft, raising the total to over 200.
CAG, in collaboration with the Civil Aviation Authority of Singapore (CAAS), will work closely with airlines and industry stakeholders to maintain Singapore Changi Airport's status as a premier global hub, increasing its city links from around 160 to over 200 by the mid-2030s.
