Heathrow is the busiest airport in the United Kingdom and the third busiest airport in the world (as of 2011) in terms of total passenger traffic, handling more international passengers than any other airport around the globe. It is also the busiest airport in the European Union by passenger traffic and in Europe only two airports exceed it in the number of traffic movements; Paris-Charles de Gaulle Airport and Frankfurt Airport. Heathrow is the Southeast's main airport, having replaced RAF Northolt. Together with Gatwick, Stansted, Luton and London City, more than 175 million passengers have travelled in total, making the London region by far the busiest city airport system in the world. The airport sustains 76,600 jobs directly and around 116,000 indirectly in the immediate area, and this, together with the large number of global corporations with offices close to the airport, makes Heathrow a modern "aerotropolis" which contributes an estimated 2.7% to London's total "Gross value added".
