I have a quick follow up. I've been watching the upgrade list all day. For most of the day the BF cabin was shown as booked "Full" and all seats were taken on the seat map. A couple of hours ago it switched to booked to 14+1 blocked and seat 4F shows as empty. If it's the case that a revenue passenger booked 4B as the last available seat at the time, and 4F has now opened and won't be filled with an upgrade, at closing will they then force the revenue passenger in 4B into 4F to comply with the pilot contract?
