I can't seem to get a specific answer from either NW or CO so maybe someone here can help.

I'm NW Plat and have been fortunate enough to get upgrades when flying CO but I am booking using my WP number which along with my status appears on CO BP's. So obviously the mileage goes on my Worldperks account.

I want to buildup my OnePass mileage but don't want to loose my Plat upgrade opportunities while doing so.

Can I have it both ways ?
