Cool777's right, since Swissair got a new website they removed seating maps, beats me why. Sorry I don't have that info either. Maybe someone else has a flight schedule booklet, they have seating charts in there, and maybe they can scan it for you.
Used to be that if you downloaded their timetable program from their website, it would have complete fleet information including seating charts. Don't know if that's still there with all the changes at Swissair.
