Back in the day, junior pilots did indeed tend to do low credit two man trips over weekends, plus some time assignable days to get them somewhere near a credit protected CAP. Under JSS, junior pilots are doing low credit trips over weekends, plus a couple more trips. 6 long haul trips in a month did not happen for junior pilots in days of old. Weekend working is to be expected because two sevenths of our work is over weekends. However it is wrong that senior pilots can do 4 trips with time in the bunk to help with the fatigue, whilst junior pilots are doing 6 trips because the credit system deems that to be the same amount of work.
