I own and live in my own home. My wife has a well paid job in the local community and does not want to move. My next posting is too far for me to commute daily (45 miles each way - but due to poor roads it would take 1 1/2 hrs each way) so I plan to serve as married unaccompanied. However, there are no Mess facilities in the area.
DrainSniffer is right on the money. The 50 mile limit is the clincher. However you may be able to argue the case that your circumstances warrant a waiver, but it will have to be argued. You live within 50miles of your new posting, you have no automatic right to SSSA or FIA.
Is it not 50 miles and/or 1 and a half hour travel time? Not sure, just asking, as I know someone who has the full SSSA and FIA entitlement and his house is only 43 miles away but it takes him over an hour and a half to get to work. (yes he does live at the back of beyond)
