Korean Air will resume nonstop flights between Seoul Incheon and Oita, Japan on October 25, 2026, restoring a direct link to Kyushu hot spring country for the winter season. The airline said on September 11 that the seasonal service will run four times a week through March 26, 2027, using an Airbus A321neo, according to SEDaily.
The decision for travelers is simple: a nonstop to Oita is back on the table for winter trips built around Beppu and Yufuin, so compare it against connecting itineraries through Fukuoka or Osaka before you lock in dates. For background on the carrier, see the airlines hub.
- Announcement date: September 11, 2026, when Korean Air confirmed the winter season return.
- First flight: October 25, 2026, from Seoul Incheon to Oita.
- Frequency: Four round trips a week, on Mondays, Wednesdays, Fridays and Sundays.
- Season window: October 25, 2026 through March 26, 2027.
- Aircraft: Airbus A321neo with 182 seats, including 8 in Prestige Class.
Seoul to Oita Schedule: Days, Times and Flight Numbers
The outbound service leaves Seoul Incheon at 9:15 a.m. and lands at Oita Airport at 10:50 a.m. the same morning. The return leg departs Oita at noon and touches down at Incheon at 1:45 p.m. Published schedule data lists the pairing as KE2177 and KE2178, operated by an A321neo, as reported by AeroRoutes.
The four day pattern covers Mondays, Wednesdays, Fridays and Sundays in both directions. That spacing suits long weekend trips as well as week long stays, since travelers get a nonstop option at both ends of most seven day windows. Morning arrival in Oita puts visitors in Beppu in time for lunch, while the noon departure back to Seoul keeps the last day useful.
Independent reporting on the restart matches the airline statement on every load bearing detail, including the October 25 start, the March 26 finish, the four weekly frequencies and the exact departure times, according to AviationBizz. When two separate outlets and the schedule filings agree this closely this close to launch, the timetable is firm enough to book around.
A321neo Layout: 8 Prestige and 174 Economy Seats
Korean Air is assigning a 182 seat Airbus A321neo to the route, with 8 Prestige Class seats at the front and 174 economy seats behind them. The A321neo is the workhorse of the carrier regional Japan flying, so the seat map will look familiar to anyone who has flown Korean Air short haul in the past two years.
The morning departure timing makes the cabin choice matter. Prestige buyers get a proper business seat for a short daytime hop, while economy passengers trade down in space but keep the schedule advantage of a 9:15 a.m. departure that no connection can match. Either way, the aircraft type is confirmed, so seat maps shown at booking should reflect the A321neo layout rather than a placeholder.
Kyushu Network Grows to Five Served Cities
Oita becomes the fifth Kyushu city in the Korean Air network, joining Fukuoka, Kumamoto, Nagasaki and Kagoshima. That density matters because it turns Kyushu into a genuine multi city region for Seoul based travelers: fly into one city, ride the trains across the island, and fly home from another without backtracking.
A Korean Air official tied the restart directly to that strategy, saying the restored Oita link completes air connections to five Kyushu cities and gives customers a much wider range of itineraries to choose from. The airline added that it will keep expanding its route network with options built around how customers actually travel.
Oita Prefecture sits in northeastern Kyushu and markets itself as Japan leading hot spring region, with Beppu and Yufuin drawing winter visitors for open air baths, seasonal scenery and regional food. A nonstop timed for the winter season lands exactly when that demand peaks, which explains why the carrier framed this as a seasonal return rather than a year round addition.
| If you… | What to do |
|---|---|
| Plan a winter hot spring trip to Beppu or Yufuin | Price the October 25 nonstop first, since it removes a connection each way. |
| Build a multi city Kyushu itinerary | Pair the Oita arrival with a departure from Fukuoka, Kumamoto, Nagasaki or Kagoshima. |
| Connect onward from Seoul Incheon | Use the 1:45 p.m. Incheon arrival to reach afternoon long haul departures. |
| Travel on a tight fare budget | Read the Korean Air fuel surcharge change taking effect October 1 before you ticket, since it can add up to 265 dollars to some fares. |
Fares and Booking Timing for the Winter Season
The restart is a capacity story as much as a convenience story. Four weekly nonstops add a meaningful block of seats into a hot spring market that otherwise funnels through Fukuoka, and early bookers typically get the lowest buckets before winter demand sets in. Travelers with fixed January or February dates should shop soon after inventory loads rather than waiting for the October start.
Watch the total fare, not just the base price. Korean Air raised fuel surcharges effective October 1, so tickets issued for these flights will carry the new surcharge levels. On longer connecting itineraries the surcharge can reach up to 265 dollars, which can outweigh a small base fare advantage on a rival routing.
Award travelers should check Korean Air SKYPASS and partner availability for the Monday, Wednesday, Friday and Sunday pattern, since seasonal leisure routes often open limited award seats that go quickly. Paid or points, the booking window that matters is now: the schedule is published, the season is fixed, and winter Kyushu demand is predictable.
October 25, 2026 is the first flight gate. Book trips starting that date or later on the nonstop; earlier departures still require a connection.
October 1, 2026 is the fare gate. Tickets issued from that date carry the higher Korean Air fuel surcharge, so compare all in totals now.
March 26, 2027 is the season end gate. Spring trips after that date need a different routing until the carrier extends or repeats the season.
