We have the "F" seats, 1K and 2K, on an upcoming flight SFO to LHR in April. I booked these tickets a long time ago, so far the seat assignment has not changed. Do I need to proactively change to a "regular" C seat so as not to get stuck in the middle four, or will this flight,
#901 , get Polarized? In this case I need to watch like a hawk because some of the Polaris seating is not good.
