"The boss of Heathrow’s biggest customer, British Airways, only discovered that building the airport’s planned third runway would require the demolition of his airline’s head office after looking at a map."

Guardian:

Both IAG and British Airways are based at Waterside in Harmondsworth, which opened in 1998 at a cost of £200m and sits in a 115-hectare (280-acre) manmade park. Walsh said the HQ was “a fantastic environmental achievement on our part”.

However, it looks unlikely to stay that way. “The first I saw of it was when the Airport Commission report came out and I saw a map and I thought, that looks very close to Waterside,” Walsh said. “Then I discovered it actually went right through Waterside.”
