Delta is mil-friendly. I'm fortunate that I have a very flexible reserve unit, and I can pretty much drill as little or as much as I want, so long as I meet the mins for the year. I have talked to some AF guys (flying the same aircraft) who are required to give 5-8 days a month or more, so Delta is used to the requests.

As long as you don't abuse it by taking it last minute, using it to drop the undesirable trips, using it over holidays, or do something stupid like non-rev with your wife to Hawaii on Delta when you're supposed to be drilling (an actual story I've heard), you should be fine.

Anybody who's actually had experience want to chime in?
