My previous experience with LA has been good (for their boarding passes to carry my FF # and status), but patchy for Mrs og (who has a multi word surname). Not only with LA but with BA, TG and UA amongst others, if it not an identical match between the FF account name and the ticket name, only the FF number appears on the BP and not status. This means the "system" does not recognise the status and you have to chase the points after the flight. Worse still, it is not consistent from flight to flight even on the same carrier.

Others who know more about the complexities in the programming areas might be able to add to this.
