Coordinates & Bearing

San Francisco sits at 37.7749°N, 122.4194°W, while Honolulu is located at 21.3069°N, 157.8583°W. The initial compass bearing from San Francisco to Honolulu is 252° (WSW), so a great-circle flight path leaves San Francisco heading roughly WSW. Because the Earth is curved, the actual heading shifts gradually along the route — pilots and navigation systems update it continuously instead of holding a single fixed compass bearing.

The latitude difference is 16.47° and the longitude difference is 35.44°. Each degree of latitude represents about 111 km, which is one reason cross-latitude routes feel longer even when the map looks similar to east–west journeys.

Halfway Point

This is the great-circle halfway position — the spot where you would be exactly 1,927 km from each city. On long-haul flights this point usually falls over open ocean or remote terrain, which is why in-flight maps often look "empty" mid-route.
