When does construction start and what is being built?

Works are planned to start in January 2026, focused on a major terminal upgrade. Expect more security lanes, gate capacity, and improved passenger flow. Phasing should keep operations running while adding space and technology that support higher throughput up to the approved cap range by 2040.

How could the Stansted Airport expansion affect airline routes?

More stands and slots let airlines add frequencies and test new city pairs. Low‑cost carriers may deepen European coverage, while seasonal leisure and VFR markets could grow. The result should be better schedule choice and resilience during disruptions, subject to aircraft availability and demand.

What are the biggest risks to the plan?

Key risks include planning conditions, environmental obligations, cost inflation, and contractor capacity. Traffic demand can also swing with the economy and fuel prices. Watch for clear phasing, thorough testing periods, and on‑time procurement awards that lower delivery risk and keep the programme on schedule.

Which sectors beyond airlines might benefit?

Non‑aero retail, food and beverage, parking, car rental, and airport advertising often benefit from higher footfall. Nearby hotels and logistics parks may see stronger occupancy and rents. Construction, engineering, and security technology suppliers can also gain through multi‑year build and upgrade contracts tied to the programme.
