SQ 21 and Full Moon
Am I correct in thinking that the best time to fly SQ 21 from EWR to SIN is when there's a full moon, preferably during the winter solstice? Would there be much moonlight flying August 30? Full moon but I am worried about the hours of moonlight in the northern latitudes.
The above is all predicated on SQ 21 actually being a polar flight! If all it does is take a short cut across the Yukon, won't matter too much.

The Winter Solstice only arrives on or about December 21 each year, but the polar night begins much earlier than that.

The actual route taken is different in each direction and stays well away from the north pole in order to take advantage of prevailing eastbound winds in each direction.

If` taking advantage of upper level winds, does this mean that EWR-SIN will fly across Greenland heading east and the return flight SIN-EWR overfly Alaska or regions adjacent, making the return trip a shortened RTW jaunt?

There are four polar routes ("tracks"). None fly directly over the North Pole, although Polar 2 comes very close.
There are minimal winds in the polar regions, which is an attractive proposition for the airlines and allows longer-range flights due to dimished fuel burns.
The SQ flights between SIN and EWR are certainly trans-polar flights along one of the four tracks established by ATC in accord with ICAO agreements and regulations. Depending on winds aloft, the decison may be made to short-cut around the polar route using a traditional route, but that will not be the norm at all.
For a chart of the polar tracks, see: Polar Flight Tracks

EWR->SIN probably will use one of the fixed "polar routes".
SIN->EWR definitely will fly further south across the Pacific to catch the tailwind, despite a slightly longer route. CO's HKG-EWR flight does that, and so does the graphics given on SQ's website.
