How is it possible that my flight was delayed for not having a crew?

18. Try following the weather. The entire country has been in a steady stream of huge

weather systems that have been disrupting scheduled flights in and out of airports everywhere. (Plus it's peak travel season.) No doubt the airplane you were scheduled to fly out on was brought in by a crew that had finished its time on duty and left for home. The new crew was more than likely delayed on their incoming flight, sitting at an airport that was iced in, fogged in, or in the midst of a blizzard. They can't get there until they get there, (maybe not at all) and a "reserve" crew has to be called in. Each individual crew member has to be called by telephone, get into uniform, get in their car, and drive (sometimes an hour away or more) to the airport, get checked in, and get to the gate. If I were an agent in the midst of all that chaos, I can't imagine trying to explain this to a passenger in a line of 60 folks trying to rebook. While they shouldn't bite your head off, travel-savvy folks understand that it's a complicated process. They try to understand how tough it is for all concerned.
