Whether the non-status holders are repeat passengers, or (more likely) one-off passengers, that cohort is still taking up 1/3 - 1/2 of the seats.
I went from PLT to DM this year and jumped an average of 7 spots on the UG list on regional 737 flights and was frequently #1-5 out of 50-80 for 1 seat. Assuming that at least a few pax in F are DM to begin with, I’d venture a wild guess that 3-5% of all pax flying a weekday business flight out of ATL are diamond.
