Question to the Department for Transport:

To ask the Secretary of State for Transport, how many additional passengers his Department estimates will travel (a) to and (b) from the North West using the international connections served by an expanded Heathrow Airport.

In 2040, compared to no expansion, around an extra 150,000 passengers could make one-way trips to, or from the North West using international connections offered by an expanded Heathrow. Approximately 120,000 of these additional trips would be to long haul destinations, and roughly 22,000 of these for business, rather than leisure.
