Every recent flight delay I've experienced was due to mechanical issues or flight crew availability (scheduled crew was delayed on another flight, available crews had or would exceed mandatory hours limit, etc). As frustrating as these are, I'm not sure I want the decision-makers thinking "Gee, this delay will cost us thousands of dollars. Fuck it, send the flight!". These mechanical checks and crew hour limits are there for a reason. And let's be honest, regulations are only as good as the enforcement. This may not necessarily be a good change for consumers.
