Next, if you’re thinking about trying to spot people in person, and you hope to run into top-tier entrepreneurs and billionaires, you might consider Beijing Capital Airport.

Not sure if it’s because of that incident earlier where someone reportedly used a plane to ram into the China World Trade Center, but Beijing’s no-fly zone may be expanded further to 300 km. Private business jets—which many enterprises and celebrities depend on—will only accept government takeoffs and landings with letters/official documentation. In the future, no matter how rich or famous you are, you’ll still have to buy tickets, check in, and board the plane together with everyone else.
