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

A nonstop flight from Detroit to Seoul generally takes around 14 hours 40 minutes to 15 hours 25 minutes, depending on the travel date and operating schedule. Flights depart from Detroit Metropolitan Wayne County Airport (DTW) and arrive at Incheon International Airport (ICN).

Delta Air Lines currently provides nonstop service on this transpacific route, with seven departures per week. The journey covers approximately 6,600 miles (10,600 km) and takes travelers directly from Michigan to South Korea without an airport change.

The large time difference between the two cities also affects the itinerary. Travelers leaving Detroit around midday normally reach Seoul during the afternoon of the following local calendar day.

How Long Are You in the Air From Detroit to Seoul?

Travelers can expect to spend approximately 15 hours in the air on a nonstop Detroit-to-Seoul flight.

The published duration is not identical throughout the year. Current schedules show flight times ranging from roughly 14 hours 40 minutes to 15 hours 25 minutes, depending on the particular timetable.

Departure times can also change by schedule period, with current flights leaving Detroit between approximately 11:25 AM and 12:50 PM.

A typical journey pattern is therefore:

Detroit around midday → approximately 15-hour nonstop flight → Seoul the following afternoon

Weather, transpacific winds, air-traffic routing and daily operating conditions can cause the actual time in the air to differ from the scheduled duration.

Why Incheon (ICN) Matters for Detroit to Seoul Flights

Travelers searching for flights to Seoul may come across two airport codes: ICN and GMP.

For a nonstop journey from Detroit, the important airport is Incheon International Airport (ICN).

DTW → ICN
Nonstop service available

Incheon is South Korea's principal international gateway and receives the current nonstop flights from Detroit.

DTW → GMP
Connection required

Gimpo International Airport (GMP) is another airport serving Seoul, but there is currently no nonstop Detroit-to-Gimpo service.

This distinction can be useful when comparing search results. A flight listed simply as Detroit to Seoul may arrive at either airport, but only the ICN route currently provides a nonstop journey from DTW
