Well, what do you propose, exactly? How much would be enough? 12? 14? 20? I mean, if it's 20, what if I go back to the hotel, immediately go to sleep, wake up 6 hours later, and can't get back to sleep? Now I'm going in to work after 14 hours of being awake...that's not Safe! I often hear complaining about duty/flight time regs, but I rarely hear a proposal as to what should be done.
