Distance between Seoul and Hanoi

Flying non-stop from Seoul to Hanoi

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

Flight distance: 1,702 miles or 2739 km

Flight time: 3 hours, 54 minutes

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. For a long distance, this appears as a curve on the map, and this is often the route that commercial airlines will take so it's a good estimate of the frequent flyer miles you'll accumulate as well.

This is a medium length flight, so unless you have a nice private jet, you might be booking 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.

Seoul to Hanoi 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: Incheon International Airport (ICN)

Arrival airport: Noi Bai International Airport (HAN)

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: 91 minutes

Getting to your destination: 40 minutes

Now finally, let's look at an actual flight from ICN to HAN on Korean Air 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: 3 hours, 54 minutes

So now we can finally get an idea of the total travel time from Seoul to Hanoi 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: 8 hours
