Offices in London are set to benefit from Heathrow’s expansion, which will allow 60,000 more aircraft to use the airport each year.
The government is expected to give the redevelopment the go ahead despite fears local residents will suffer from increased noise levels.
John Stewart, chairman of pressure group Clear Skies, has claimed the government has not been transparent about the effect the expansion will have.
“It would be the biggest change to flight paths since Heathrow opened over 60 years ago, but it is being done by stealth. Most people who will be affected have no idea what is in store for them,” the Times reported he said.
London is served by a number of airports of which Heathrow is the largest. Although flights can arrive closer to the city centre if they can touch down in North Woolwich at London City Airport.
Heathrow’s owner BAA has been told it may have to sell some of its airport portfolio to help improve competition.
