Work rules my friend. I drop a four day usually around a drill weekend or when I want to go in and fly extra at my army unit. Swap and vacation touching are another great perk. Believe it or not bidding reserve is a great way to get time at home if done smartly (technically not days off though). Rarely do I ever fly the line I was actually awarded and I always end up with higher than min guarantee. Like I said, picking up premium time on my days off is a big bonus at the end of the month.
Everyone's mileages will vary but I did my research and am very happy with my individual situation.
