Airspace warnings · Flight options

This direct polar route avoids major rerouting corridors and their congestion. Compared to alternatives routing through central hubs, it offers a more direct path when airspace conditions permit.

The flight goes east from Tokyo, not west: across the North Pacific, north of Alaska, over the Canadian Arctic and northern Greenland, then down past Iceland into the UK.
It avoids Russian airspace completely, which is why it heads out over the Pacific instead of straight across Siberia.
No connection — one aircraft the whole way.
The polar corridor is around a third longer than the straight line between the two cities. That is the cost of going around a closed sky rather than through it.
Total trip is around 13 and a half hours.

Route dependency Some

This routing exists because Russian airspace is closed to it. Rather than crossing Siberia it goes the other way round — east over the Pacific and across the Arctic — which is what makes it so much longer than the straight line.
