Similar flights to NRT are available ex SFO, DEN, etc.
Just because (a) I love an odd routing and (b) the Mercator projection has really warped my understanding of geographic relationships (and I'm kind of vague about Guam to begin with... hopefully I'll solve that problem by visiting some day

) -- what does that do to flight time? E.g. is it a comparable reroute or does it add/subtract x hours? My brain is telling me it probably adds at least several hours but I'm not convinced...
