Distance calculator

Travelmath helps you find distances based on actual road trip directions, or the straight line flight distance. You can get the distance between cities, airports, states, countries, or zip codes to figure out the best route to travel to your destination. Compare the results to the straight line distance to determine whether it's better to drive or fly. The database uses the latitude and longitude of each location to calculate distance using the great circle distance formula. The calculation is done using the Vincenty algorithm and the WGS84 ellipsoid model of the Earth, which is the same one used by most GPS receivers. This gives you the flying distance "as the crow flies." Find your flight distances quickly to estimate the number of frequent flyer miles you'll accumulate. Or ask how far is it between cities to solve your homework problems. You can lookup U.S. cities, or expand your search to get the world distance for international trips.

Driving non-stop from Boise to Portland

How far is Portland from Boise? Here's the quick answer if you are able to make this entire trip by car without stopping.

Nonstop drive: 428 miles or 689 km

Driving time: 6 hours, 33 minutes

Flying non-stop from Boise to Portland

Now let's assume you have a private jet and you can fly in the fastest possible straight line between Boise, Idaho and Portland, Oregon. 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: 344 miles or 553 km

Flight time: 57 minutes

The straight line flight distance is 84 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 1/6th 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.

Boise to Portland 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: Boise Airport (BOI)

Arrival airport: Portland International Airport (PDX)

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: 10 minutes

Getting to your destination: 18 minutes

Now finally, let's look at an actual flight from BOI to PDX on Alaska Airlines 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, 9 minutes

So now we can finally get an idea of the total travel time from Boise to Portland 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: 4 hours
