5-600 flying hours plus 2-300 dead head hours ..... that do not count towards your annual limit -> This puts me off the list!
Unstable rosters and more changes are a given with cargo ops, but there has to be a limit as to how they can push me around dh, with changes and cancellation, otherwise it's a handy tool to optimise crew usage. If dh would be fully counted, they would try to minimise disruptions and changes.
No requests -> No go either!
Reserve -> Has to be redefined more clearly.
Leave -> I guess that would not be a bigger problem than on the regular fleet.
