SFO>CLT - 4 and 5 out of 6. No one cleared.
CLT>DCA - 2 and 3 out of 12. Top 2 cleared, so one of us moved up to FC after being seated in coach. The gate agent did make it sound like there would be an open middle seat in the event of this happening, which is why we said yes to being split up, but that was not actually the case and someone was put in the vacated middle seat.
