Even worse, you can get caught with no return flight. In late 2001, I was flying back home to Dallas from Prague, connecting in Brussels. And the airline I was on, Sabena, declared bankruptcy the very day of the flights. I got lucky, if your flight left before 8am you were rebooked on a different airline. After 8? You were out of luck and on your own. My flight had been scheduled for 7:50.
