If I have one beef with our Reserve program, it's this: pilots with <300 hrs in a given airplane need to fly. One or two short trips per month on Reserve, IMO, isn't enough to lock in a good a/c habit pattern when you're new to the bird.
What do you, esteemed colleagues, think of not assigning reserve flying to pilots with <300 hrs in a given bird/seat? The pilots just above them on the seniority list would get the Reserve lines, but over time that'd become part of the cost of doing business wrt to getting new guys up to speed.
