Just to add a data point, I am lowly MVP and my current bookings- 10 segments. I already have the bulkheads and exit rows booked, and I am in there for my AS mainline legs, but it is showing no availability in any of the exit rows or bulkheads if I want to move my seats around. My QX segments seem ok, I am still able to move around 1A,B/2A,B alright
