OP good luck with that. UA would rather sell a TOD than given out a CPU. Take today as an example, flew ORD-SFO and booked a B fare and applied an RPU. 24 hours out, F=6 but by time for flight left, only one upgrade processed and I was 7th on the list. For the life of me, can't even use my RPUs. I try but always fail to SFO even on slower travel days. SFO is near impossible in my books.
