After reading this thread I called asap to Istanbul to get a good window seat for my IST-HKG Comfort Class flight. No queue, no on hold, the guy in the 24h reservation center was service minded and prompt for my requests ^. I´m surprised positively; although in near future customer should be able to reserve his/her seat online like I do with LH, SQ and other. But I´m happy now, got best seats...
