A cramped, dirty little shithole of an airport. Terminals two and four should be bulldozed.
Heathrow is probably the worst airport I've ever been to. I'll go back to Gatwick or Stanstead.
1) The busiest airport in the world.
2) A place to go during a heatwave if you want to pass out.
1) "Dude, we're going to Heathrow!"
2) "Dude, I wanna die." "Dude, let's go to Heathrow."
