Below is the Swiss seat map for an upcoming flight I have in J class; ExpertFlyer says some of the Row 4 seats that have an X are blocked, not occupied. Anyone know when they'd be open for selection, given the flight departs in ~72 hours or so? I'm in a throne seat in Row 12, but would love to land a bulkhead seat as I want the extra leg room and don't love the suffocating feeling in the throne seats. Thanks!
