(to USA)<-Tokyo-Soeul-Beijing-Taoyuan-Hong Kong->(to Singapore, Malaysia)
Welcome to the corridor! This is one of my favourite location to fly. This is a special place to me, and I also found some good stuff happening. Tokyo Haneda is the hub in TS.
Something good:
Even in TS, no trolls
Intense Traffic when Asians are awake
Great flight connection airports
Something worth paying attention:
Headwinds when fly south. Usually average out at 120 knots.
Welcome to Asia, where jet stream happens.
