OK, new (or maybe old) question but I cant find the answer by searching.
I'm confirmed in biz (paid) and have used a GUC for a companion in a different PNR. Ticket has been reissued etc. Now my plans have changed and I need to go, potentially, on a different flight. What happens to my "companion" who is obviously, no longer a companion. Not trying to pull a fast one, but since already reissued and in a different PNR from the get-go, any ideas on if it will stick? thx
