Question to the Department for Transport:

To ask the Secretary of State for Transport, what is required for an airport to be designated as a level 3 airport.

For an airport to be designated as Level 3 slot coordinated, and therefore requiring the formal allocation of slots by an independent coordinator, the demand for operating services should exceed the airport infrastructure’s capacity for at least one scheduling period. Secretary of State approval is required to designate any airport as Level 3 slot coordinated.
