How Much Time Does a Flight from Detroit to Seoul Usually Take?

A nonstop flight from Detroit to Seoul generally takes around 14 hours 45 minutes to just over 15 hours, depending on the individual schedule. Flights leave Detroit Metropolitan Wayne County Airport (DTW) and arrive at Incheon International Airport (ICN), the principal international gateway serving Seoul. Current route data place the distance at approximately 6,617 miles (10,649 km).

Delta Air Lines currently operates the nonstop DTW–ICN route. As of August 2026, flights are scheduled seven times per week, averaging one direct departure per day.

Travelers can also reach Seoul with one connection. Some of the shorter current alternatives take approximately 17 hours 10 minutes through Montreal, 18 hours via Salt Lake City, or about 19 hours 20 minutes through Minneapolis. Other routings through Atlanta, Vancouver, San Francisco, Tokyo and Toronto can take around 19 to 21 hours or longer.

For passengers primarily interested in reaching South Korea as quickly as possible, the nonstop flight usually offers the simplest journey because it eliminates both the transfer and the waiting time between flights.

Average Duration of a Direct Detroit-to-Seoul Journey

A direct DTW–ICN flight normally requires about 15 hours of scheduled travel time.
Current route schedules list the fastest nonstop journey at approximately 14 hours 45 minutes, while other timetable data put certain services at just over 15 hours.

The direct route connects Detroit Metropolitan Wayne County Airport (DTW) with Incheon International Airport (ICN) without an intermediate stop.

The airports are approximately 6,617 miles (10,649 km) apart. Current August 2026 schedules show the quickest nonstop journey at around 14 hours 45 minutes.

Delta Air Lines is presently the only carrier operating this route nonstop. Current schedules show approximately one DTW–ICN flight each day, although departure times can vary according to the date.

Flying directly can save several hours compared with most connecting itineraries. It also removes the need to navigate another airport, change aircraft or allow additional time for a transfer.

For a journey covering more than 6,600 miles, these time savings can make the nonstop option particularly useful for travelers who want the most straightforward itinerary.

Passengers who choose an indirect journey can connect through Montréal–Trudeau International Airport (YUL).

Some of the quickest DTW–YUL–ICN itineraries take approximately 17 hours 10 minutes in total, making Montreal one of the shorter current one-stop alternatives to the nonstop flight. Air Canada is among the carriers offering this routing.

On faster schedules, the Montreal layover can be around an hour, which helps keep the total journey below many other connecting options.

Even so, travelling through Montreal adds more than two hours compared with the fastest direct flight.
Passengers should check the complete elapsed journey time before booking because a longer transfer at YUL can significantly increase the total duration.

Salt Lake City International Airport (SLC) provides another connecting option between Detroit and Seoul.

Some Delta itineraries using the DTW–SLC–ICN routing take approximately 18 hours, including a connection of a little over an hour on faster schedules.

Passengers may also travel through Minneapolis–Saint Paul International Airport (MSP). Current schedule data show some DTW–MSP–ICN journeys taking around 19 hours 20 minutes, including the transfer.

Both options take longer than the nonstop DTW–ICN service, but they can provide useful alternatives when direct seats, fares or departure times do not suit a traveler's plans.

The layover makes a major difference on these itineraries, so two flights connecting through the same airport may have noticeably different total journey times.

Travelers have several additional connection points available if they do not choose the direct Delta service.

Depending on the airline, schedule and departure date, possible transfer airports include Atlanta, Vancouver, San Francisco, Chicago, Tokyo Haneda, Los Angeles, Toronto, Dallas/Fort Worth, Seattle and New York.

Some representative faster journey times include:

Around 19 hrs 35 mins via Atlanta
Around 19 hrs 50 mins via Vancouver
Around 19 hrs 55 mins via San Francisco
Around 20 hrs 20 mins via Tokyo Haneda
Around 20 hrs 20 mins via Los Angeles
Around 20 hrs 41 mins via Seattle
Around 20 hrs 45 mins via Dallas/Fort Worth
Around 20 hrs 47 mins via Toronto

These are examples of faster scheduled combinations rather than guaranteed travel times. Some connections can extend well beyond 21 hours if passengers have a longer layover.
