Well, I guess for larger types, (IL-62, Tu-154, Tu-134, you know, anything larger than 80 seats) they are mostly correct, but smaller types (specifically, smaller than 20 seats, the capacity is questionable for an airline, though most of these smaller types had their information taken from JAWA and were added at the end of the 2000s round, then again these could be high density versions where the passengers are sitting facing a different direction than they normally would (faced towards the side of the aircraft as opposed to the front).
