I understand. This was actually a deliberate decision. The graphics in the gallery pages show the seat counts for each primary cabin class, so in the case of AS the seats marketed as Premium Class are included in the economy class count. This is consistent across the site, and applies to Iberia’s XL, AA’s Main Cain Extra, and Finnair’s Economy Comfort seats. When you open the seat map, the number of PC seats is explained in the header narrative.
