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.
