Because of my short redeye into Tokyo, I actually wound up going to bed early and somehow managed to wake up after sleeping about 8 hours. This left me with a few hours to kill in my hotel room, eating breakfast at my hotel, and then finally a few more hours to kill at the airport.
Star Alliance carriers share much of the check-in space at the south wing of Terminal 1. I arrived at the terminal a bit before the three hours prior to departure mark and saw that Turkish was assigned to the same check-in area as Air China. After a highly choreographed changeover, check-in opened and I was advised to relax in the United Club until my flight began boarding.
