For a Shikoku trip from Korea's Chungcheong region or southern Gyeonggi, the original report highlights Cheongju–Matsuyama nonstop flights in October 2026. Aero K's non-scheduled service was planned for 6 round trips on Wednesdays, Fridays and Sundays from October 14 to 25. From the source date, the first departure was 41 days away, but the schedule depended on approval by both countries' aviation authorities. Recheck the flights in the airline's booking system before fixing hotels.

According to operating information updated September 2 by the Korea Tourism Organization, Aero K RF3863 and RF3853 were scheduled on October 14, 16, 18, 21, 23 and 25. These were non-scheduled flights offered for individual booking through the airline website for departures from Korea.

All departure and arrival times are local. Korea and Japan have no time difference. Weather, airport conditions or approval could change flight numbers and times; the issued booking confirmation is the final reference.
October 25 was added after the earlier announcement
Because the sources cover different dates, this account uses the Korea Tourism Organization's September 2 update. Aero K is the operator, so the airline booking screen's dates, times and fare rules take priority when purchasing.
Possible round-trip combinations in the source
Friday return
October 14→16 or 21→23. These suit a short trip focused on central Matsuyama and Dogo Onsen.
Wednesday return
October 18→21. This allows a day around the entrance to the Shimanami Kaido or toward Uchiko, alongside Dogo Onsen.
Sunday return
October 14→18 or 21→25. With flights only on Wednesdays, Fridays and Sundays, a standard Friday–Tuesday 4-night combination is unavailable in this notice.
Wednesday return
The source lists October 16→21 or 18→23 here, offering more time for Matsuyama and other parts of Ehime. Note that its own timetable identifies October 18 as Sunday, so the second pairing does not match this Friday-departure heading.
Return October 25
The original calls this the longest simple round trip within the announced dates. Its list also contains earlier outbound dates, so that description is internally inconsistent and needs checking rather than being treated as a confirmed booking recommendation.
no later return on this route in the notice
No Matsuyama→Cheongju date after October 25 appears in this announcement. For a one-way journey, secure a return route through another Japanese airport first.
Check that both outbound and return flights are on sale in the airline search. Non-scheduled services may have seats remaining in only one direction, so check both together before hotels.
There is no fixed officially announced airfare
Check the booking screen
The September 2 official update gave no minimum or fixed promotional fare. Dates, remaining seats and fare selection change the total.
Compare the inclusive total
Look beyond the search result's base airfare to taxes, fees and the round-trip total on the final prepayment screen.
Check by fare type
A lower fare may exclude checked baggage or have stricter change/refund conditions. Save the rules of your selected fare with the reservation.
The account does not fix a travel website's momentary low fare as an article price, since seats, currency and fees can change. Use the final KRW total on Aero K's official payment screen.
Matsuyama Airport to the city: recorded costs
The airport's reference journey times are about 15 minutes to JR Matsuyama Station, 20 minutes to Matsuyamashi Station and 40 minutes to Dogo Onsen. Traffic and flight arrivals can change them. With planned arrivals at 17:20 or 17:30, the source suggests focusing the first evening on checking in around Matsuyama or Dogo rather than a long onward journey.
Conditions for travelers to check
Individual booking available in the announcement
A travel agency sold all seats on the previous June service, but October was announced for direct sale through the airline website.
No
This is an ordinary international ticket from Korea to Japan, not a Korean-passport discount or a benefit restricted to Japanese residents.
Available
Aero K's official website provides Korean. The update did not separately state a particular card-company discount or overseas-issued-card restriction; that absence is not proof that every card is accepted.
Check for an exact match
Enter the passenger's Latin-letter name exactly as in the passport and prepare the passport and Japanese entry procedures applicable to that traveler.
Before booking
- Check that RF3863 and RF3853 actually appear in Aero K's official booking system.
- Search outbound and return seats together across the updated 6 dates: October 14, 16, 18, 21, 23 and 25.
- For an October 25 Cheongju departure, note that this announcement contains no later Matsuyama→Cheongju flight.
- Choose changeable accommodation in view of the schedule's conditional approval by both countries.
- Compare the final total including fuel surcharge, airport taxes, baggage and seat costs, not only airfare.
- Save checked-baggage, change, cancellation and refund rules before payment.
- Allow for immigration, baggage collection and the city transfer on arrival day, avoiding a tight late reservation.
- The day before returning, recheck airline operations and bus times to Matsuyama Airport.

EDITOR'S NOTE · EVERYDAY TRIP
EVERYDAY TRIP Editorial Team's advice
With only 6 round trips, the preferred return could sell out first. Secure both directions in the airline system, then choose free-cancellation or changeable accommodation while considering the approval condition.
An afternoon arrival and evening return leave limited sightseeing time on a 2-night trip. Combine Dogo Onsen, Matsuyama Castle and Okaido, leaving the Shimanami Kaido or Uchiko for 3 nights or more.
No return on the same route after October 25 was announced. Before buying that Japan-bound flight, calculate time and extra cost for ferries, trains or highway buses to another departure airport such as Hiroshima, Takamatsu or Osaka.
Schedule changes can affect a non-scheduled flight itinerary more than a regular-service trip. If the difference between the lowest fare and one including baggage is small, compare the actual total together with baggage, change and refund terms.
