NOTE: When booking, erase your Avios number when entering your passenger information. This will make it much simpler to add your AA Advantage number at a later time.
Tried and I couldn’t do that. Finnair keeps saying:
The booking reference you entered is not valid. Make sure you are entering a Finnair booking reference.
Tried using both my BA and AA reference number. I did just book the tickets two hours ago (if that makes a difference).
