Heathrow says expansion is "urgent" for UK growth, but plans are heavily criticised over environmental concerns.

Of all the infrastructure projects that have failed to get off the ground in this country, none has tested the patience of the British public quite like Heathrow’s proposed third runway. It has been 22 years since it was first reported that Labour ministers were “seriously considering” expanding London’s major airport.

BA’s owner says Arora’s plan for shorter third runway at Heathrow is ‘credible’ - International Airlines Group chief executive Luis Gallego said ‘competition is good to improve things’.
