Flying non-stop from Cerritos to Diamond Bar

Now let's assume you have a private jet and you can fly in the fastest possible straight line between Cerritos, California and Diamond Bar, California. Because of the curvature of the Earth, the shortest distance is actually the "great circle" distance, or "as the crow flies" which is calculated using an iterative Vincenty formula.

Flight distance: 19 miles or 30 km

Flight time: 6 minutes

The straight line flight distance is 6 miles less than driving on roads, which means the driving distance is roughly 1.3x of the flight distance.

Your plane flies much faster than a car, so the flight time is about 1/3th of the time it would take to drive.

This is a relatively short flight in a private plane, but you might be planning to book a commercial flight. In that case, your travel time would really need to include how many minutes to get to your local airport, wait for security, board and taxi on the runway, land at the other airport, and get to your destination.
