Willie Walsh, head of global airlines industry body IATA, lambasted Britain's Heathrow Airport, calling it a "greedy monopoly hub" and describing its plans to raise airport charges as "outrageous."

Since leaving British Airways parent company IAG last year to run the International Air Transport Association, Walsh has continued to bang the drum against passenger charges at Britain's busiest airport, Heathrow.

Addressing an audience at the Aviation Club in central London, he said Heathrow was trying to place the financial burden of the COVID-19 crisis on its customers by proposing to raise airport charges by 90% to 42 pounds per person.
