We're flying tomorrow SEA/FLL (AS 38). That flight has been missing from the schedule for more than a week - which usually means it is already full/oversold.

Today you can see who is waitlisted for tomorrow. Out of 30 so far on the waitlist, 18 have been upgraded to the Premium seats. To my little pea brain that means that 18 premium seats had to have been available, and now that they have been filled, there must be 18 random seats in the back that are now empty. Right? Or close?

But the flight is STILL not showing as bookable when you do a search for tomorrow.
