Flew the inaugural DTW-HND flight last Thursday 6/16.
Since Row 31 was completely blocked ahead of time, I kept 44J (exit window), and decided not to pay the $60 (charged for Gold Medallion) Economy Comfort fee. FYI, row 44 on 772ER has tons of legroom even at the window--the door doesn't protrude like it does on the 744. The rest of Row 44 was completely empty, save for 44AC.
There were about 100 empty seats in Y on my flight!
