Anyone had experience with star RTW claiming points/status on velocity and points on KrisFlyer?

Anyone had experience with star RTW claiming points/status on velocity and points on KrisFlyer? I'm flying Singapore MEL - SIN, SWISS SIN - ZRH, SWISS ZRH - YUL and Air NZ YVR - MEL. What I want to do is claim points and status credits on velocity for the Singapore and Air New Zealand legs and KrisFlyer points on SWISS then transfer to Velocity. My concern is, when I booked I used my Velocity number (I'm velocity gold) but have since joined KrisFlyer to try and get something from the SWISS flights. Now when I log onto my KrisFlyer account my Singapore booking shows with my KrisFlyer number and unable to Change back. I only want to earn KrisFlyer points on the SWISS flights. Any tips or suggestions to ensure this happens and I don't all of a sudden accrue a heap of points and status on my KrisFlyer account? Thanks

Just change it when you check in or at the desk. Just make sure that it is printed on your boarding pass, and double check in the Krisflyer lounge. A couple of times I've asked at the check in counter for the VA number to be added instead of KF, and when I've got to the lounge to double check it wasn't done. 

Awesome. Thanks rob01
