But that is not case for me and several other posters here. I think the extra time zones due to crossing the date line when flying to Asia outweigh any benefits from flying in a western direction.
It is the total # of time zones (i.e., distance) crossed and the direction that matters. Simply crossing an imaginary demarkation (International Date Line) has no effect. You can test that out by crossing the equator, another imarginary demarkation.
