Tiers don't matter... and you don't put in :"EBD" in any FFP form... just the FFP# like 111111111 or whatever that might be. AI will look it up and know you're *G or *S or a nobody. Also, almost nobody allows you to change FFPs after you've entered it once till the check-in time. AI is of course more restrictive in not allowing other *A FFPs to be entered even once.
