It also seems the what’s the difference question mark where United confirms buy ups pay extra PQM IS GONE.

the checkout screen has a note that says miles based on original fare class now. This could save me a lot of money wasted on paid upgrades for double PQM. I did it almost every flight to make 1K last year and prob spent $5,000+. Obv also enjoyed being in First.
Just did one of the online upgrades....glitches out and had to call, ended up double charge, one will fall off, got the double PQM, but no miles on the buyup portion of cost.
