My airplane config for a Sunday flight has been changed to the 787-9 and the old business class (yay /s). Row 13 has a window seat available which I’ve read seems to be better than the others as you don’t have to climb over anyone. Row 7 isn’t available. Given the options, should I go for 13K (window seat)?

Bonus question: FLUB seems to exist on this flight but all the seats are greyed out. Any chance of moving to one of these seats closer to check in? I’m not exactly that important status wise (bronze).
