Just to report that the recent changes on Plusgrade points/miles not changing with the upgrade seems to have come into effect, at least when crediting to ffp other than EB.

My recent outbound flight upgraded with minimum cash offer did not credit automatically to A3 (as has previously always been the case).

When the return flight credited automatically a few days after I knew something was up. Went to retro-register and the system picked up the original booking class (not A). It’s ‘just’ 1200 miles, but still a bummer.
