Chk Airman...
At EK, they don't get any credit for the month for all bunk time doing these ULR's they talk about. They get paid but no credit. So, while a max month might be say 100 hours, they only credit for say 85 meaning the company can (and absolutely does) roster them for more flying.
117 hours in the jet - credited for only 90 - paid for 117.
