How to estimate it

Singapore is at 104 degrees east and New York at 74 degrees west, almost exactly opposite sides of the globe, so the shortest route passes near the North Pole. From Singapore, at 1 degree north, to the pole is 89 degrees; from the pole down to New York, at 41 degrees north, is 49. 89 + 49 = 138 degrees, and one degree is 111 km: 15,300 km. The actual distance is about 15,000 km.
