Skybus: How cheap is too cheap?

On Christmas morning, two planes of the start-up cheaper-than-cheap-fares airlines Skybus were out of commission. These things happen to all airlines, right? Usually, stranded passengers catch a later flight, or the airline arranges a seat on a competitor's flight. Inconvenient, sure, but not the end of the world.

Then there are the Skybus passengers. You see, Skybus only has seven planes total, so there were no other Skybus flights to move them to. And Skybus, being the cheapest airline, doesn't have reciprocity arrangements with other airlines to provide seats for its passengers in such situations.

Worst, Skybus does not have a customer service department, no phone number you can call for help. All passenger contact is via the internet, not much help when stranded in the terminal.
