Panther is spot on. I have on more than one occasion been rostered more than 100 hrs a month . So anyone who disputes this is quite simply lying .
The rosters are unsustainable . Even though our colleagues on the 330/340 are not doing as many ULR's ( if any) and that their rosters are as a result not likely to be over 100 hrs a month , they are substantially more brutal given the number of night turns etc. The F/O,s overall are working a little less ,but still hard.
Having said this though , I did laugh when a brand new Captain offered to pick up a trip of mine( turnaround) in return for a day off. I was curious why , so he told me he was in a hurry to get his 500hrs PIC so he could go to KAL ! , LOL.
The real toll is going to be long term sickness , and we will continue to see policy change to adapt to increased sickness ( and not to the benefit of those that are ill). How long do you think you can continue to fly 900++ hrs a year , multiple polar , night turns etc . 5 years , 10 years , 20 years ?
If I was an actuary doing some sort of projection , I would be worried.
