<p>i got to tell another american "heathrow only has two runways" the other day</p><p>they operate at 98% capacity</p><p>it's the 13th busiest airport in the world on movements ~450000/year, comparable to schipol, which has six runways, heh</p><p>and to avoid stacking planes around the city, incoming flights are advised to slow down by ATC, so that they arrive just in time for their slot, heh</p>
