Heathrow may add 25,000 flights a year before third runway

Airport reveals plans as it launches a new consultation on its expansion

An extra 25,000 flights a year could come through Heathrow before the third runway is built, in plans revealed by the airport as it launched a fresh consultation over its airspace and operations.

Planes could come in to land on both runways at the same time during busy periods, Heathrow has proposed, to help maximise its capacity ahead of expansion.
