I live in Philadelphia and if I want to visit a friend in Chicago for a weekend, it will cost me several hundred dollars for a round-trip ticket on U.S. Airways. For significantly less money, I could book what’s known as a “hidden city” ticket from Philadelphia to Orlando via Chicago, and then just get off the plane when it stops in Chicago. Most airlines ban the practice, but there’s not much they can do to stop it. They can, however, sue to stop a website from promoting and booking these verboten fares. [More]
