Between 2015 and 2017 a) 18 domestic passenger routes and b) 51 international passenger routes have ceased operating at regional airports. These figures are based on scheduled flights departing from regional airports that operate at least weekly. With regard to domestic passenger routes, in the same period 18 routes have been created.
The proposed Airports National Policy Statement sets out an expectation that expansion at Heathrow will deliver an additional six domestic routes. Separately, the Secretary of State has set out a clear ambition that about 15% of slots made available from a new runway will be used for domestic routes.
