Hello, still a bit early but I'll be carefully looking at this one as we get a bit close.
If you take the route that is planned on Flightaware, I think the flight looks fantastic! You loop up and around all the jets. If you hit anything it will be over Greenland and Iceland for a bit and maybe out of LAX for a bit, and maybe around Turkey for a bit. Enjoy your flight! Let us know how it goes.
