Thanks for the info, Opsbod.
It does seem fairly hard for you. But I must say I would love to have 3 days off rostered together like you! I only tend to get 7 days off in 28 days which is the minimum legal requirement, and I have not had 3 days-off together since last year. I know if you count our standbys, the 'days off' will be more, but of course they're not the same. Also, one of the standbys per month usually turn into flights anyway.
Anything else you think the flight crew should know about the workings of ops/crewing?
