Flying non-stop from Aspen to Boulder

How far is Boulder from Aspen? Here's the quick answer if you have a private jet and you can fly in the fastest possible straight line.

Flight distance: 100 miles or 161 km

Flight time: 23 minutes

Compare this to a whole day of commercial travel with the airports and waiting in line for security, which ends up taking a total of 5 hours, 22 minutes.

Flying private is roughly 8.5x faster, and saves you about 4.5 hours in your total travel time.

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.

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. The flight itinerary at the top of the page takes into account all these factors to get a more accurate estimate of your actual flight time.
