Data point. 1/23 LAX-OGG pmCO. Probably 1 or 2 paid first, 8 miles uogrades, rest CPUs. No GS boarded when called. FA came straight to me in 3B. First time ever. Then went back to row 1 and front to back.
Looks like FAs are, in a lot of cases, getting first choices to GS and 1Ks. Methodology varies.
