We're getting very close to the end of the 60 advance purchase window for the few Thanksgiving sale fares that are out there. I believe that tonight at midnight might be the end since most of the Thanksgiving fares were for departures before 11/28. Already fares for departures for 11/27 and earlier have already evaporated.
Now there's nothing to stop them from refiling fares but the current filing is going away.
From my casual observations, loads still seem very weak in business class and economy.
