My wish is that someone will give me a trillion dollars and tell me to have fun with it. Our wishes have approximately the same likelihood of coming true. As the thread about Air China apparently selling some domestic first class seats in O shows, they can't even get consistency across the designated award buckets.

Note that under AC's current "branded fare" monstrosity, the poster upthread who said that this applies to Tango fares is incorrect -- although it wouldn't surprise me if that changes, as I'm sure it's what AC would prefer. Domestic flights in S, T, A, L, K will give 0 PQS, regardless of whether they're Tango or Flex. AC now publishes both Tango and Flex fares all across their fare ladder, so if you care about UA earning, you have to be very careful as to what you're buying.
