From past experience, no. I have a dormant SK account so when I make a reservation on SAS website it automatically picks up my Eurobonus number. On a recent CPH-SEA flight which I booked on SK website, I changed the FF number to BD at check-in. Even though the BP had BD*G, miles were posted to SK. Could not get the miles transferred to BD as BD said miles once posted to another program can not be posted/trasnferred to BD.
