Gatwick Airport is aiming to increase passenger numbers significantly as part of its extensive expansion plans.
The plans could see the airport's capacity rise to 75 million passengers annually by the late 2030s.
The last major investment was a £250 million upgrade to the airport's railway station, completed in November 2023.
Emergency runway set for major upgrade
The crucial part of Gatwick’s new expansion plan is the transformation of its emergency runway.
This runway—currently mainly used for taxiing to and from terminals or when the main runway is shut for emergencies or maintenance—will be moved 12 metres north.
This shift is necessary to meet aviation safety regulations and will bring the standby runway into regular use for departures of narrow-bodied planes like the Airbus A320 and the Boeing 737.
Currently, Gatwick operates one main runway and the emergency runway as described above.
As one of the busiest single-runway airports worldwide, Gatwick is heavily utilised, which leads to limited spare slots during peak times.
Runway operation disruption can lead to widespread knock-on effects due to the high level of usage.
New terminals, taxiways and aircraft gates
The upgrade is not limited to the runway—the airport also plans to remodel and replace existing taxiways, extend both terminals, and install new aircraft gates.
In terms of transport infrastructure, Gatwick has pledged to enhance road connections to both terminals.
The plan is to create fly-overs that separate local traffic from airport-bound vehicles.
On the other hand, the railway station, which underwent a £250 million upgrade, was completed in November 2023.
How many more flights and passengers will Gatwick handle?
The planned enhancements mean Gatwick’s air traffic capacity will climb to around 386,000 flights a year—around 100,000 more than current levels.
This expansion in service translates to a projected increase in annual passenger numbers, rising from the current circa 43 million to around 75 million by the late 2030s.
How much will the Gatwick expansion cost?
This expansion won't come cheap—Gatwick estimates the total cost of the plan to be around £2.2 billion.
However, according to Gatwick’s public commitments, the airport will privately finance the project and will not increase airline charges to cover the costs.
Flights could take off from the enhanced runway before 2029.
Heathrow rivalry and future challenges
The owners of Gatwick Airport, French company Vinci and investment fund Global Infrastructure Partners, stand behind these ambitions.
Gatwick will likely face competition from Heathrow Airport, which also has its own expansion plans, including a third runway.
However, progress at Heathrow may be slow despite recent governmental support, leaving Gatwick determined to boost its own capacity ahead of its rival.
What could the expansion mean for local communities?
While details of the exact environmental impact and consequences on residents or the office and working environment are not included in this report, these are certainly important topics up for discussion as the expansion progresses.
The planned expansion is likely to bring both opportunities and challenges, and Gatwick Airport and its owners will need to navigate these carefully.
The airport will remain a site of significant activity in the coming years, with the potential to handle an increased number of passengers and flights once the expansion is underway.
However, the effects on the wider community and the future of air travel in the region remain to be seen.
