NW standard is 50K US 49 to Europe, and "Europe" goes east to Moscow.
SEA-DTW-FRA-SVO is 7329 each way. If they let you add FAI-SEA it would add 1530 for 8859 total each way, but this routing does not pull up on nwa.com
Or take the Southern Route, one stop from LaLa Land to NyetNyet Land on on Skyteam DL: LAX-ATL-SVO is 7334 each way. 14,668 miles = 3.4 FF miles/mile flown.
Why anyone would want to do it, and on DL metal, is another question for their shrink to explain to us.
For flyrights: "around 9,500 miles, 40,000 miles OFF season award... which is around .23 award miles per mileage flown" I believe you mean 1 / 0.23 = 4.2 award miles per mile flown. (9,500 x 4.2 = 40,000)
