If UA sells no more tickets or buyups, there should available for upgrades a minimum of 7 Polaris seats plus Polaris seats put aside for PP oversell (if any) .
Maybe crew rest accounts for extra seats and 42 is actually the number of passenger-occupiable seats?
That explains much, thank you! There are many more seats showing available on the seat map that the screen shot shows.
I appreciate the information.
