The only little problem I see with the military is that your spouse can't develop professionally, that person must be a stay home person because there is not much around the air force bases. Also they don't get to fly much, the typical fighter pilot finish its career with 3-4000ish hours when the civil guy finish with 5 times that.
Airlines give you the freedom that the air force will not give you. once you have some seniority you can be home for a week or more not worry about much and you can live in any city you want.
At the end I think it depends on your long term goals. Air force flying is awesome but freedom is restricted---specially for family members. Airline flying is like a non-stop vacation but it doesnt have good job security.
Hope it helps
