I’m just back from a trip where I booked and paid cash for WT+ and used a GUF2 to upgrade to CW (and paid the extra taxes). At check in I paid cash to upgrade to F.

Just wondering what tier points this scenario ends up with. I got 90 for the return leg (so WT+ tier points).

I know you should get the tier points for the cabin you actually booked, but haven’t spotted any posts that cover the situation where you pay to upgrade further.
