I've been with the airline for a number of years, and I put a lot of time into my Reserve career. I'm up front with Delta, send my orders for 30+ day commitments as far in advance as I can, and don't act like a jerk.

The only comments I've ever gotten from the CPO's office have been along the lines of, "Let us know if we can do anything to help you while you're gone." Playing by the rules and treating people with common courtesy goes a long way.
