Full breakdown →The nonstop Los Angeles to Tokyo route crosses the North Pacific — entirely clear of warning areas with no active airspace concerns on any segment. JAL, ANA, and United all operate this corridor daily with strong flight frequency and more choices if something goes wrong. Preferred choice for most travellers on this route.

Full breakdown →Korean Air and Asiana via Seoul add a world-class North Asian hub break between Los Angeles and Tokyo. Seoul's airport is consistently top-rated; the Seoul to Tokyo second leg is only 2 hours over clean airspace. Useful when nonstop options are sold out or for connections beyond Tokyo.
