Craggenmore for the punters you're more or less correct but as this thread is about pilot conditions I think it's only right to mention an airline where you're actually credited for time spent in the bunk and where you get more than a 24hr layover for the majority of destinations. 24hours rest (which I'm told actually turns out to be less) after a DXB-JFK is absolutely insane IMHO and bordering on the criminal.
