Flying to Korea (on orders): Travel in Uniform or Civies?

I have been assigned to Korea, and am going unaccompanied. &nbsp;This is my first OCONUS assignment (other than 2 deployments) and would like some insight on this.<div><br></div><div>I ask this because I have always understood that when traveling on official business (i.e., on orders) you do so in uniform. &nbsp;In the past that meant Class A or Class B. &nbsp;I also remember the 80s when traveling in uniform was discouraged for PERSEC reasons. &nbsp;</div><div><br></div><div>So what advice do you have on this issue?</div>
