I dont know about you guys, but 135 rules protect me from being forces to do stuff like that. How do the 121 rules stack up against 135? If we fly over 10 hours of FT/14 hour duty day since we signed on, we are kindly asked if we can return the airplane and if we say no, we're tired, they say alright get some rest and bring the airplane home... how does that work in the 121 world?
