Osaka to London is 5,923 miles (9,532 km), a flight of about 13 hours 45 minutes.
The right side benefits from a strong Osaka Bay departure sequence and, during the long Siberian cruise segment, passing views of the Ural Mountains and the southern edge of the Lake Baikal region — genuine terrain drama largely absent on the ocean-heavy alternative sightlines. The left side's London arrival is excellent but shorter in duration than the cumulative scenic value on the right.
Flight Path
