When its about money, they actually start early. My flight for Nov 30:
Note that row 6 is not paid, while row 7 is. Also note how many seats have been taken in EC. Almost unbelievably many. Would the auto-seat-chooser for the default seat been forgotten, and it still hands out seats from the first row by default?
Edit: And note that it says 15 EC seats free, while I only count 13?
