IMO, the difference is that TSA is a privately owned business vs. these other airlines. If the business fails, the owner takes a personal hit/loss whereas these other CEO's just take their farewell bonus and move on. Bad as it's been, TSA has withstood the test of time and they continue to be profitable even if it has sometimes been at the expense of their employees. Who knows about longevity but as I said, it's not as easy for a privately held business to just shut down like they did Comair. The regional airline business has been cut throat and much as we hate it, TSA's penny pinching has kept us in jobs (most of us).
