My stupid question is why do Asian, Russian and Arabic Airliners fly east from Los Angeles (LAX) some over US states others up to Canada Newfoundland and over the Atlantic Ocean, down towards Europe then down towards there country. Its seams like a long route instead of heading west over the Pacific Ocean at least on the global map it looks shorter. I saw these routes being taken on FlightAware from LAX.

Which specifc destination are you thinking about? The shortest route for LAX-DXB is over the pole (east from LA):

LAX-UUDD is similar:

LAX-ZBAA does go west:

But as soon as you get farther into Asia than about Mumbai, it's shorter to go east from LA:

Also, winds may play a role. See here how SIN-EWR-SIN is/was flown eastbound both ways, because of winds.

Winds play a big factor. Routes can vary widely from day to day depending on the location of the jetstream. Distance isn't the only consideration. It often makes sense to fly a significantly longer route if it benefits from strong tailwinds. That's why many flights from the east coast of North America to Asia use the shortest polar routings westbound, almost overflying the North Pole, but on the eastbound trip they take the traditional transpacific route near Japan and Alaska.

Winds, temps, ETOPS divert routes, engine out drift down, and other factors contribute to routing.

Thank you very much to all of you that replied. I now understand how airline routes work. I was just a little confused but you all cleared it up. Thank you
