This does not sound unique to Southwest, I imagine all airlines have to do this to get people staged in the right places. Which means our air travel system is basically a just-in-time system and as we've learned JIT systems break quickly when there are shortages. Software problems and a lack of schedulers may be contributing to this event, but it seems like it could happen to any airline and is something of an infrastructure weakness in global transport. In fact, airlines might sometimes book flights for pilots and attendents on competitors planes, which may mean the lack of flights by Southwest could affect other airlines placement of personnel, so there may be some contagion risk.
