I once flew Los Angeles to Bangkok and we didn’t fly over any part of the Pacific! There were two massive lows over the Aleutians and the Bering Sea, that had 150 knot westerly winds!
Our route was north over California, Oregon, Washington, British Columbia and the Yukon. We coasted out over the Beaufort Sea, coasted in over Siberia and flew over Kamchatka, the Sea of Okhotsk, China and Thailand.
