On this episode of Run the Numbers, CJ and Ben trace corporate private jets from Sam Walton’s scrappy two-seater to Alex Karp’s $17 million jet bill. They break down when flying private actually makes business sense, how jets hit the balance sheet, the tax and accounting implications, what companies disclose to investors, and when executive travel crosses the line from productivity tool to corporate excess.
