Right, arriving in the US during daylight hours is the objective, being the dead of winter when going there and everything in the house is dead cold and dormant after ten or eleven months, turn everything on and stock up. Transiting through ICN is always quick and short and never experienced any hangups with KAL either, though the only drawback is the 787 long haul, prefer airbus. On the return, same with little layover time, land cnx @~10pm warm weather, go home eat and go to sleep.
Personally, the contrast of the two, going there and the return are two completely different situations. And for whatever reason, the burn-out jet lag seems worse traveling eastward.
