Question to the Department for Transport:

To ask the Secretary of State for Transport, what proportion of passengers at Heathrow Airport in (i) 2030, (ii) 2035 and (iii) 2040 will be international-to-international transfers in scenarios (a) without and (b) with a third runway; and what assessment she has made of the potential impact of those passengers on the economy.

We are currently reviewing the Airports National Policy Statement (ANPS) and plan to consult on a revised ANPS in summer 2026. The Department plans to publish updated aviation passenger forecasts alongside the consultation. In reviewing the ANPS the Department is considering the potential impact of expansion at Heathrow airport on the economy.
