I'm booked in F on several AS flights, and while AS may be capping sales, as far as I can tell they aren't actually blocking any seats in F at all. They allowed two pax to book seats immediately adjacent to me on one flight - I was in 4D on E75, and these idiots took 4A and 4C. I've moved to row 2, but have also made duplicate bookings on WN and will likely fly them instead.
