It's almost T-72 for lax-jfk. F has 5 seats open. J has 1 spot open.

What are the chances J gets upgraded to F and a few more go from Y to J? Is it common? When does it happen?

I'm a lowly gold this year so it's very unlikely for me but curious if they do move J to F to open up space.

I figured they would have done by now so they could sell J for last minute travel.

If it matters, Y looks more than half empty.
