I'm happy enough to be indifferent on good-airline (JL, NH, SQ, CX, QR, EY, EK, etc.) in newer lie-flat all-aisle business class, and usually happier-than-on-ground in F (esp on something like JL). Premium Economy or economy-with-empty-seats-next-to-me is fine as long as I have good audiobooks and headphones. I recently did SFO-HND on JL 1 in F (Alaska miles redemption for SFO-HND F, KIX-BKK in C, for 75k miles or about $1250). It was better food than all but the best restaurants, great service, decent Internet, and a comfortable, large seat which turned into a very nice bed. Doing that for 20-40h would be no problem at all.
