I find SK's configuration within europe funny. You have 3 classes, Business, Econonmy Extra, and Economy; but you get situations, like on my last flight to SVO, where all 3 classes are in front of the curtain (3 rows of biz, 3 rows of economy extra, 1 row of economy), and economy exclusively is behind it. IT's just funny to have 3 cabins so close to eachother.
