Flying non-stop from Deadwood to Boulder

Now let's assume you have a private jet and you can fly in the fastest possible straight line between Deadwood, South Dakota and Boulder, Colorado. 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: 311 miles or 501 km

Flight time: 52 minutes

The straight line flight distance is 72 miles less than driving on roads, which means the driving distance is roughly 1.2x of the flight distance.

Your plane flies much faster than a car, so the flight time is about 1/5th 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. Scroll down to see a more realistic calculation that takes into account all these factors to get a more accurate estimate of your actual flight time.

Deadwood to Boulder airports and flights

In the quick calculation above, we assumed you had a private plane and just wanted to know the time in the air from city to city. But for most of us, we're going to be flying on a commercial airline (whether it's first class or coach). So that means we really need to account for all the extra travel time getting to the airport, waiting for our flight, and making it to the destination.

To give you a better estimate of real-life travel, we've put together a flight itinerary with actual airports. Eventually you'll be able to customize this plan, choosing your own airports and flights. But for now, here's an example we've selected to give you an idea of how traveling might work between airports.

Departure airport: Rapid City Regional Airport (RAP)

Arrival airport: Denver International Airport (DEN)

With the airports selected, we can estimate the travel time to and from the airport, based on how far the airport is from downtown.

Getting to the airport: 121 minutes

Getting to your destination: 100 minutes

Now finally, let's look at an example flight from RAP to DEN and figure out how long it would take to fly including take-off and landing, and time to taxi on the runway.

Commercial flight time: 1 hour, 14 minutes

So now we can finally get an idea of the total travel time from Deadwood to Boulder including time spent getting to/from the airports, an estimated wait time of 2 hours at the airport for TSA security lines and waiting at the gate, and the actual flight itself.

Total travel time: 7 hours
