Right now I see 6K in J Class, 80K & 82A in W Class as free. Hope that helps.

Zippy is that looking at the seat map? Some seats aren't released until 24 hours before the flight. 747340 as a member of V-Flyer have you used your free ExpertFlyer searches?

Expert Flyer is showing:

J5 D5 Z3 W3 S3 K3 Y7 B7 L7 M7 Q7 X7 N7

So looks like there are seats in Upper, including Zs so maybe a miles opportunity to upgrade, but very limited in PE and lots in economy.
