I booked a reward ticket through Aeroplan (AC) for a flight in December. They have me booked on SK903 - ARN-EWR, only problem is according to SK's timetable and Gallileo this flight does not operate then, and ends Aug/Sept. I only discovered this when I tried to find the seating config for the A330.

When does SK update their sched for winter? BTW I am in row 7, is that ok or should I try and get a better seat?
