In retaliation Russia closed its airspace to countries that sanctioned it.
There was a crazy post of the flight path of a plane from Tokyo to London. It flew out into the Pacific, through the Bering Straight, along the Arctic Ocean and then to London. That’s a lot of fuel.
I think it is time for Euro lines to close. They won’t compete with Asians on half of their routes.
They used to do that all the time during the Cold War. Then the Russians figured out that they could price their overflight rights just a little bit less than the dollar value of the fuel saved, and make out like bandits.
