I noticed that quite a few flights from EWR to FLL this Sunday have wide open FC cabins - including a couple 757-300s. Even PBI is showing a good amount of available seats, given so many FC seats on that route are booked at full Y.

My EUA did not run, and it does not appear anyone elses' did either - the flight I am on is totally wide open - only one seat taken. Is it possible some of these flights are being totally missed by the system and will run the day of departure or possibly cleared by the GA? It seems quite odd, because usually this flight clears for me at the Plat time window, and by Friday there are usually only 2 or 3 seats left open. I have never seen the cabin that empty a couple days before departure.
