The reason I say this is because ive noticed on one of my flights the following:

So I'm leaning on saying that the opups and upgrades go to checked in, but not in booked.
Or maybe the eups go to booked, and opups go to checked in.
Who knows really.
The booked number comes from another system. It is the number of available seats minus the number left for sale. Sometimes the J1-9 number is moved manually due to Y being oversold or onloading. So there might really be J5 but Y is -9 or something. They blank it to J0.
