normal worker has 52 weekends plus 12 public holidays (or more depending on the state) plus 4 weeks annual leave
that is 144 days off a year (about 40%)
pilots get 42 days off (about 12%)
i hope you are not a captain if that is the way you look at data before you, you think we should go from 12% down to 8%. An airline managers dream.
Please tell me you were on the whisky when you wrote that.
