Yes, it should say "BKKCS" in smallish print, and "UA*G" in larger print, at the very bottom of the boarding card stub. I'm guessing that the FF# was entered incorrectly (somebody else probably got credit for your flight; am waiting for the post "Why did I get credit for this TG flight?" ). Always hand the card to the TG agent, or have it visible to them. You can ask for a print-out of the record, in order to verify the correct FF#.
