Does SQ 21 from EWR to SIN via Atlantic or Pacific ocean? It will make sense to fly over Atlantic because wind direction.

Neither, over Acrtic Ocean (polar).

Actually that is incorrect. Flight SQ21/22 is a true round the world flight. SQ21 goes over the Atlantic and Euroope. SQ22 returns over the Pacific.

Very rarely does it take the Polar Route, unless the winds are against it heading east.

according to Great Circle Mapper ( which does not always reflect the actual route flown ) the route would be on the "Atlantic" side of the pole rather than the "Pacific" side .

Some kind person told me once how to post maps from the great circle mapper ... but being the dopey @#$#%*^ I am I have managed to delete the instructions .. otherwise I would post the map .

Hint hint hint to any kind person who would like to give me the instructions again  

I promise to take better care of them this time

SQ 21 goes EITHER transpolar or transatlantic, depending on winds and/or European ATC constraints. The return almost always goes Transpacific

It goes over the Atlantic and down through Northern Europe.

SIN-EWR goes up over Japan and Alaska and down through Canada, unless they've changed the route since I flew it earlier this year.

I recently flew EWR-SIN-EWR on SQ 21/22 and it used a polar route on the EWR-SIN leg and a Pacific route on the SIN-EWR leg. It all depends on winds of the day.

On SQ21 we took off from EWR and headed directly north on a polar route. We passed very close to the North Pole and then came down through Siberia, passed over Mongolia, then headed through China (directly over Wuhan) and then into the South China Sea passing just east of Vietnam before landing into SIN. Total air time was 17hrs and 40min.

On SQ22 we took off and headed northwest over the South China Sea, directly over Naha, then on very close to Tokyo before heading more westerly. We stayed south of the 60 parallel and a good distance south of ANC. We crossed into North America just south of Vancouver before paralleling the US/Candian border. We finally crossed the border close to Buffalo NY before heading into EWR. Total flight time was 18hrs 20min (but some of that was due to delays on arrival into EWR as the flight time should have been closer to 18hrs)

You can read the trip report that I wrote for the flights if you want more information:

If you have never designed an airplane part before, let the real designers do the work!

Pieinthesky & RoseFlyer,

I think your both correct, will depend on the time of year and the location of the polar jet stream.

I flew this route last month. It was a Pacific routing, crossing Taiwan, Japan, passing just south of ANC, across Canada to Toronto, and then into JFK.
