What are your opinions with Soldiers wearing ACUs to the airport...should it be allowed?

So here are my thoughts, my understanding is wearing your ACUs during off duty hours is unauthorized on off post establishments with the exception of picking up an item or 2 from the store on your way home.  Shouldn't this also apply to wearing your uniform to the airport?  I get it, you are coming home on R&R during a deployment, and those are just certain exceptions that are made for those on a year long deployment.  My issue arises from Soldiers who are not deployed going on leave or pass, and wearing the ACUs to the airport to gain favor and recognition from the airline.  We all want to benefit for our military service and what we have done for our country while wearing this uniform.  I've been on 4 deployments (3 to Iraq and 1 to Afghanistan), but even when I go on regular leave or pass I always wear appropriate attire while traveling.  I'm not sure if your Soldiers are up to date on their AT level 1 training, but specifically states that we should not being wearing anything that may draw attention to us while we travel whether it be abroad or with the continental US.  This is a serious OPSEC violation, and we as Officers and NCOs should be letting our Soldiers know that they should not be traveling in ACUs.  I travel abroad often, and to see a Soldier who is going on leave flying on the same flight as me makes me nervous, because they do not know who is watching.  I am quick to pull that Soldier to the side and tell them who I am and explain to them that they should not be wearing that uniform while traveling because it draws attention to them and the others that are on the same flight.  I see it as if we are no longer putting decals on cars because it draws attention to us as servicemembers and makes us a target, than wearing this uniform in an airport or any where outside of a military establishment draws just the same if not more attention as the decal on our cars.  What are you thoughts?
