On a recent trip SFO-HKG HKG-JFK I was lucky enough to get op-uped Biz->F on the outbound, but not the return. I'm wondering how common this is, and whether it is a function of the route.

SFO-HKG F was pretty amazing, one of the best flights ever, but HKG-JFK Biz was a littke below expectations. Seat was just a little too small for me to strech out, the seat controls were slightly broken (one of the controls was crossed with the adjacent seat!) and I felt like there was not enough staff to respond to requests or serve meals promptly...everything was a bit slow. And really not enough food served for a 16 hour flight...they ran out of the snack service items. Surprising. But overall the flight was OK, no major problems.
