Just completed a PVG-PEK-FRA-ORD-ATL-IAD-FRA-KIX-PVG trip using UA miles with the following LH F legs

PEK-FRA: A380
FRA-ORD: 747 (New F)
IAD-FRA: A330 (Old F)
FRA-KIX: 747 (New F)

Had a blast combined with some great crews. The A380 cabin is fantastic, and I felt I could do yoga in the bathroom. I appreciate the touches such a personal lockers, and complete black out curtains between the galley (cough cough UA).

The 747 New F gives an insane amount of space, I think it may be the most personal space in the sky, along with SQ Suites, alebit with a lot less privacy. The bed is what gave the edge to the 747 to the A380 for me. Never have I slept so soundly on a plane before.

The highlight was FRA-KIX where I was the only passenger in F. On the top deck of a 747, it felt like a private jet!

Food was eh, interesting. I'm not into fancy food so it was a little much for me. I wrote up a TR I'll post soon.
