Travellers passing through Cape Town International Airport (CPT) in Cape Town should prepare for a major construction phase starting in March 2026 and running until 2029. The project forms part of a nationwide airport modernisation programme led by Airports Company South Africa (ACSA) - and while the long-term benefits are significant, the next three years will bring noticeable disruption.
How much will the upgrade cost?
ACSA has confirmed a R9 billion investment specifically for Cape Town International Airport (CPT), forming part of a wider R21.7 billion national airport infrastructure programme across South Africa.
Key cost breakdown announced so far:
- R6.1 billion: New realigned main runway
- R2.4 billion: New domestic terminal development
- Additional funding: Expansion of the international terminal, upgraded security, aircraft stands and infrastructure
This makes the Cape Town upgrade one of the largest airport investments in the country since the 2010 World Cup expansion.
Why the airport is being expanded
Cape Town has seen strong travel demand and growing long-haul connectivity. Airlines and airport planners have flagged increasing congestion in terminals, baggage systems and aircraft parking areas. The upgrade is designed to expand capacity and future-proof the airport for long-term tourism growth.
The major upgrades in simple terms
Terminal expansion and passenger flow improvements
Construction begins with upgrades to the domestic arrivals area, followed by broader terminal expansion. Travellers can expect:
- Larger domestic and international terminal capacity
- Improved baggage handling systems
- Upgraded security infrastructure
- More space to ease peak-season congestion
A brand-new runway
One of the most significant developments is the construction of a new, longer runway costing more than R6 billion. This will allow:
- More flight movements
- Accommodation of larger aircraft
- Growth in long-haul routes
New domestic terminal infrastructure
A new domestic terminal (valued at R2.4 billion) will significantly boost capacity and ease congestion during busy travel periods.
Expanded airside and airport infrastructure
Additional upgrades include:
- Expanded aircraft parking stands
- International terminal expansion
- Modernised security and airport systems
Together, these projects represent one of the biggest upgrades in the airport’s history.
How construction will affect travellers
Cape Town International Airport (CPT) will remain open throughout the works, but passengers should expect temporary disruption until 2029.
Likely impacts include:
- Changing terminal layouts and signage
- Temporary walking routes and construction zones
- Longer walking distances
- Busier passenger areas at peak times
Travel tips for the next three years
If you’re flying via Cape Town between 2026 and 2029:
- Arrive earlier than usual (especially for international flights)
- Follow airport signage closely
- Allow extra time for check-in, security and boarding
- Monitor airline updates and allow flexibility
The long-term payoff
Once completed, travellers can expect:
- More flights and improved connectivity
- Reduced congestion
- Faster baggage and security processing
- A modern, larger airport ready for future travel growth
Bottom line: Expect short-term inconvenience - but a significantly improved Cape Town International Airport (CPT) by the end of the decade.
