I finished a TPAC in 85K in a 747 last trip. The bin beside it was actually the downside for me since I usually sleep against the side of the plane but there I woke up contorted into a most awkward position. Still, it's upstairs on a 747. Even though I have now been up there my fair share of times I still always get a kick out of being upstairs on a 747 since it still was my childhood dream since I was a little kid back in the 70's to someday get to ride up there.

Actually last trip was interesting since going over I flew LAX-TPE upstairs in 85K, and coming back was in Super Business 10K on a Combi CGK-TPE which is EXACTLY the same spot as 85K on the 747-400's. I can assure you that 85K is not the same as 10K though
I have to agree with
jimbo99 about the difference in service between PL and Super Business too. In CGK as I boarded when they saw my Super Business boarding pass at the door I was personally escorted upstairs to my seat by the FA, always addressed by name, ect. Really a first rate experience. From TPE-LAX in PL on a 777 the service was not nearly so personal.
I have no idea what the 744 was doing in LAX for the trip over. LAX has pretty much been exclusively 777's for a while now but they had the 747 there for at least a few days a month or so ago.
