Just used the last of my RUCs from last year for a mid-September work trip to SFO. Can't complain with their use this year -- have used all for flights to SFO (including one RT that as D1 in both direction) except one being used for a leisure trip to SXM.
My big remaining question is what to do about my 2022 PM Choice Benefit (earned PM last year). With the new rules, I'm not sure if I have enough time to use 4 more RUCs before 1/31/23 so I'm probably going to end up going with the 20k miles and then will use my 2023 PM Choice Benefit for RUCs to use next calendar year.
