I don't do the orient very frequently -- which routing is best for SFO-SIN for the easiest NC u/g with an SWU on the long segment -- connect at NRT or HKG? On the days I want, both long segments are NC0 and C9, so I'd have to waitlist for NC in either case; and both have 744s, so equal number of C seats. What's the easier u/g, SFO-NRT or SFO-HKG? And reverse?
