The route has a great circle distance of 15,349 kilometres (9,537 mi; 8,288 nmi).^[3] However, SQ24 to New York is typically flown a ground distance of around 17,250 km (10,720 mi; 9,310 nmi)^[4] over the Pacific Ocean where jet stream winds can assist; while SQ23 back to Singapore sometimes opts, instead of the westward polar route, to fly a ground distance of 16,500 km (10,300 mi; 8,900 nmi)^[5] eastward, across the Atlantic Ocean, when favorable jet stream winds assist to save both flying time and fuel. The flights are scheduled to take over 19 hours and 18 hours respectively.

The flights originally used an Airbus A350-900.^[6] On January 16, 2021, the route was changed to operate using an Airbus A350-900ULR.^[7][8]
