Heathrow expansion 'essential' after busiest May

Heathrow says expansion of the airport is "essential", after experiencing its busiest May on record.

More than 7.2 million passengers travelled through its four terminals last month, up 0.4% from a year ago.

A Heathrow spokesperson said: "As these record numbers become the norm, it's time to start an honest conversation about the challenges this presents for an already space-constrained yet highly efficient hub."

Opponents of the west London airport's expansion say increasing air travel would make it much harder for the UK to meet its climate change commitments. The Mayor of London, Sir Sadiq Khan, opposes a third runway at Heathrow for this reason as well as because of noise and air pollution.
