Within SkyTeam (most/all?) airlines share the name of the account holder with the corresponding frequent flier number. Once I accidentally tried to input my number in my wife’s frequent flier field and it gave the error that the name does not match the card holder. So not sure how this happened when flying AF/KL when Flying Blue is your programme.
