SK983 & SK984 Copenhagen–Tokyo Air Corridors
Interesting how SAS flies completely different routes between Copenhagen and Tokyo depending on direction. CPH–HND goes west of Japan via Central Asia, while HND–CPH can head east via the Arctic. All because of Russian airspace restrictions and winds i suppose.
The distance is quite similar 11800km (7 332 miles) for the arctic route and 11500km (7 146 miles) for the Asia-route and the time difference around 1 hour.
