Okay, she was right about FO being Flying Orchid, but FO is not an honorary status. I was an FO when I was Silver Medallion, FO = Silver Medallion (DL used to show the two letter abbreviation on the boarding passes when I was Silver Medallion, and I wondered what the FO was, but I knew it meant I was Silver Medallion, they've since switched to spelling out "Silver Medallion" on the boarding passes). FC (Flying Colonel) is the honorary status and she had the two confused.

Also, as I said, FC can show up with other levels because it is the honorary status, whereas FO will not show up with GM on the same passenger, because they are mutually exclusive, you're either one or the other, but that is not true of FC. Most Flying Colonel's I've seen on the manifests do have some other level of status, which is why I said you will usually see it with one of the standard Medallion levels on the manifest (such as "FO FC" or "GM FC"). A passenger can easily have up to three designations beside their name on the manifest actually, I've seen several that look like this:

Doe, John 1A GM MM FC

Which shows that John Doe is a Gold Medallion member, Million Miler, and Flying Colonel (the honorary status).
