Interesting insight ORD, it's just that I detest turbulence (I may be posting more on this topic in the future), and the few last times we flew from HKG to YYZ via TPAC the turbulence was heavy from takeoff until the west coast of Alaska, I mean can you imagine how long that was? Not to mention the particularly bad shaking over Japan.

In cases like that, I wondered why the pilot didn't just fly back with the polar route.
