Heathrow was relatively quiet yesterday, but maybe it was just this terminal. The debate for a new runway has heated up again. Should Heathrow have a new runway or would it be better at Gatwick. Boris (London's mayor and now MP ) favoured building one in the Thames Estuary. Locals at Heathrow are very anti the Heathrow option not only for the increased flights but the additional traffic on the roads. Last month more than 6 million passengers passed through here. Whatever the final outcome there will be mixed reactions.
