The straight mileage run can be done in R with a same day turn, if you take the world's longest flight twice with about 6.5 hours to enjoy Changi. Seems to get 100% PQM on UA. I've found all UA metal EWR-SFO-SIN for as low as $660 (2.9 cpm? wow!), but it takes an extra day, which I don't have. There's something bucket list-y for me taking these flights, even at what I figure to be 5.7CPM in premium economy. And if I can do it with only 2 nights away from home, even better.
