Not tried LX but SQ and TG have no problem accepting A3 as a carrier and the FFP number during OLCI. Flights posted withing 3-5 days for both airlines. even though I only have a Blue (*S) card from A3 at the moment the SQ BP showed A3*G correctly and I was even allowed to access the lounge in CGK with BP only. (I had LH*G & BD*G as a backup, but not needed in this case)
