New runways at Heathrow and Gatwick are among the options that have been short-listed by the Airports Commission for expanding UK airport capacity.
The shortlisted 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, will also consider a new airport in the Isle of Grain in north Kent.
A final report is due by summer 2015.
