The Official Aviation Guide became OAG who will have what you need in digital form but at steep commercial rates, as will their competitor Innovata (Cirium) The actual seats bit is surprisingly complex if you want accurate figures, as the same aircraft type can have wildly different numbers of seats depending on layout and class configuration. OAG/Innovata's standard schedule product has the aircraft variant normally assigned to a route shown, and they survey the airlines on the seating configurations of their aircraft calculate capacity and ASKS. I believe Cirium now cross reference this with flight tracking data to get data based on the actual aircraft used (which solves edge cases like substitutions or an airline operating aircraft with differently configured A330-200s on different routes) - doing that was part of the masterplan when I worked for them before they acquired Flightstats.
