Thanks ldsant for the explanation for this member. ROH is one of those acronyms that can fool even the most experienced traveler sometime.
If you don't mind, I'll submit it for inclusion in the FlyerTalk glossary since it appears to be missing from there.
If any of our members see other acronymsd like this which are missing from our glossary, please feel free to send the suggestions along to me or any other moderator for consideration.
For our other members, the "glossary" link is located under the "Help" menu at the top right of each page.
Thank you.
