The reason they block there calendars are they have been confronted about it by other pilots. If you look at their schedules ( before they blocked them) every trip was 2xxx for the ENTIRE YEAR, indicating they were a charter or extra trip. The vast majority of these trips begin or end (most begin AND end) with some huge deadhead. Numerous people have gone to management about this with the same response "we are aware of it." The company cannot discipline someone for flying trips. They can't discipline them for talking to schedulers. The only people that are going to be disciplined are the individuals who confront them at Ops, and they claim harassment. That is the reality. So where does that leave us, the same conundrum that has plagued pilots since the beginning. Someone will always find a way to cheat the system and screw their buddies. My only question is can Professional Standards get involved? I know one needed a 3 in 30 a few months back. How did I know? The trip (an out-and-back) was in open time for CAP with a note from scheduling saying F/O needed both legs for currency.
