The Economics of Owning an Airline

How do you become a millionaire? Start as a billionaire and buy an airline. It's an old joke and it's also the most misunderstood business in the world. Airlines look like they sell seats. They don't. In this teardown we follow the money through the entire business: why most airlines don't even own the planes they fly, the brutal fixed costs that bankrupt them in almost every downturn, and the strange truth about where the profit actually comes from — a private currency they print for free and sell to banks. By the end you'll understand how an airline can be one of the worst investments in history and one of the most durable money machines ever built, at the exact same time. 🔔 New teardown every week: we take apart a famous business or asset and show how the money really moves.
