For CX, BA, AY, RJ, UL, QR, IB, JL, QF, when you enter the FF number, Amadeus only verifies the first initial and surname. It doesn't even check the title.

However, for actually posting to the FFP, the majority of these either don't perform a second verification match, or they only match on first initial and surname.

CX and TK I know definitely check for a full name match, ie. PNR name must match the FFP account name, but very few carriers do.

Any FFP that allows free transfers between members or between accounts for consolidation (avios group) is of higher value... so QR, BA, IB, AY, QF.

VA has also been hit a fair bit with VA and AC, and VA and QR as VA allows free transfers between members.
