High Latitude Flights

[ABO944]

Hello!

I wondered if there are any flights from UK/Europe to the far east that fly up at the very high latitudes / north pole ??

If so, what would be the routing for a flight, for example, from LHR-NRT ? What countries are overflown, and what would be the chosen en-route alternates?

Whats it like flying over the north pole (apart from snowy)?

Thanks ... just interested!
