I’m reasonably new to this and having trouble figuring out how status works when flying with airlines within the same alliance and on code shared flights. For example, if I fly on a flight that’s code shared between AirNZ and Virgin, and I’m a member of both, what determines where the points and status are earned? The airline that I book through? The airline that actually operates the flight? The FF number I quote when booking (if I can provide a Velocity number to AirNZ or vice versa)? If they go to the wrong airline, is it possible to have them transferred after the fact?
