MANUAL SELL @:-)
I called CO to redeem some of my "valuable miles

". The agent asked me what cabin I would like. Despite ANA showing no F or C avaialble, I requested F. The agent said "ok, I have to request the flights and you will have to call back later to see if the award seats are confirmed."
(Fast forward to later...)
The F award came back confirmed

even though ANA showed it as not available.
So, there you go. This is why CO people have been reporting success in scoring these impossible awards like SQ 1/2 F while we UA folks just watch and drool.
That's it. Next year, all of my UA flights upgraded with SWUs and CR1s will be credited to CO.
