UK air capacity: Pros and cons of runway proposals

New runways at Heathrow and Gatwick are among the options that have been shortlisted by the Airports Commission, which is considering ways to expand capacity.

The three short-listed options include adding a third runway at Heathrow, lengthening an existing runway at Heathrow, and a new runway at Gatwick.

The commission, led by businessman Sir Howard Davies, has also not ruled out a new airport in the Thames Estuary.

Speaking to BBC Breakfast, Sir Howard explained the pros and cons of the options on the table.
