The first-class areas are the ultimate networking rooms. It starts in the lounge, where you get a proper place to relax, alongside people who are at the top of their professions. It continues on the plane, where you might find yourself sitting alongside the founder of a multimillion-dollar company or the chief executive of a Fortune 500 business. That's valuable. Last year, Chinese gaming company Da Lian Zeus Entertainment paid $2.35 million to have lunch with Warren Buffett. You'll pay a lot less to spend several hours sitting next to someone guaranteed to be a success in his or her field.
