Exactly right. Upon unfreezing my pay goes up, and secondly with 500h on type and 2500h there is always a chance of command. The second is purely down to my handling on an OPC or LPC but there is a much higher requirement for capts than FO's in my company, in actually fact they would rather have two captains flying together than a capt and a FO.
Just re-reading the replies, i'm currently flying nowhere near the 100h a month commercially, in fact thats my problem, i'm hardly flying at all, possibly 25-35 a month, which is why i want more hours
