Could the pressure on crews in the summer have something to do with how many a/c RYR expect to park during the winter? Crew up for the winter schedules, plus an X%, and hope you can muddle through the summer with no/little leave and crews filling in on days off and gamble having too few SBY's. Been there, done that; it's an old trick and will work only if everyone says yes. It's called cost saving, but they don't tell you it's being planned. What is true, it can not be sustained indefinitely. It is a short term cost saving measure, but it will bite back.
