I faxed my UA 1K card and my MilleMiglia status got updated the next day. I guess I got lucky judging by the other posts here. When I checked in in ORD my boarding pass did NOT show the CFA status, but when requested an agent in Rome she was able to do something in the system and re-printed the boarding pass which I used for lounge access.

I am afraid the same trick may not work on other SkyTeam airlines and would like to get the actual plastic card. Has anyone received it after getting the status matched? How long did it take?
