As an ex RAF Loadmaster, fixed and rotary wing, I always ask for a seat by an emergency exit both from a comfort point of view but also from a flight safety viewpoint. I know most airlines now charge a premium for such seats so I was very surprised on a recent A330-300 US Airways night flight from Philadelphia to Manchester to see all four seats, next to the mid aircraft emergency doors, reserved for Crew Rest Seats. This was only a 6.5 hour flight so some of the cabin crew only worked just over 3 hours but deprived 4 passengers from a little bit of comfort. Cushy or what?
