1A/K are generally unblocked around T-72 hours from departure. On my particular flight I opted for 1E/F as 2F is blocked as it's a bassinet seat. Every other seat in the cabin is now occupied except for 2E/F. I have no idea if booking the last 2 seats in F would result in 2F being unblocked which is where I would rather sit as it's just that little bit further away from the galley.
