The document presents a case study on systems thinking. It discusses problems in the US airline industry, including widespread flight delays and cancellations that frustrate customers and cause losses. It analyzes symptoms like growing passenger numbers and outdated infrastructure. Through tools like causal loop diagrams, it identifies the root causes as the "tragedy of the commons" situation where individual airlines overuse common resources without coordination. The suggested solution is for airlines and the government to collaborate on upgrading infrastructure, technologies, and incentives to better plan for shared resources and demand.
