Eastar Jet Opens Early Bird Sale on Japan-Korea Routes
South Korean low-cost carrier Eastar Jet is running an Early Bird Special Sale covering its routes between Japan and Korea. The booking window runs from 10:00 a.m. on September 16, 2026 through September 22. With one-way fares starting at 2,000 yen, it is a compelling offer for anyone planning an autumn or winter trip to Korea.
Booking and Travel Periods
- Booking period: September 16, 2026, 10:00 a.m. – September 22, 2026
- Travel period: November 1 – December 31, 2026
The travel window spans roughly two months from late autumn through year-end, making it easy to plan around the tail end of Korea’s foliage season, winter illuminations in Seoul and Busan, or year-end shopping. Keep in mind that demand spikes in late December, so the cheapest seats on those dates are likely to sell out first.
Eligible Routes and Lowest One-Way Fares
Seoul/Incheon Routes
- Osaka/Kansai – Seoul/Incheon: from 2,500 yen
- Tokushima – Seoul/Incheon: from 2,500 yen
- Sapporo/Chitose – Seoul/Incheon: from 4,100 yen
- Fukuoka – Seoul/Incheon: from 4,800 yen
- Kagoshima – Seoul/Incheon: from 5,000 yen
- Okinawa/Naha – Seoul/Incheon: from 6,500 yen
Busan Routes
- Kumamoto – Busan: from 2,000 yen
- Osaka/Kansai – Busan: from 3,000 yen
- Fukuoka – Busan: from 3,000 yen
- Sapporo/Chitose – Busan: from 3,500 yen
- Okinawa/Naha – Busan: from 4,500 yen
The lowest fare in this sale is Kumamoto–Busan at 2,000 yen, followed by Osaka/Kansai and Tokushima to Seoul/Incheon at 2,500 yen. International service from Tokushima is limited, so this represents a rare option for residents of Shikoku. Longer sectors such as Sapporo/Chitose and Okinawa/Naha also start in the 4,000-yen range, which is excellent value relative to the distance flown.
What Is and Is Not Included
All figures are one-way fares and exclude taxes, airport charges and fuel surcharges. The final amount payable will be higher than the advertised fare, so be sure to check the total on the booking page before confirming.
On the plus side, 15 kg of checked baggage is included in the fare. Checked bags are normally a paid add-on with low-cost carriers, so this effectively adds meaningful value for travelers planning to shop.
Points to Note Before Booking
- The lowest fares are limited in number and are not available on every flight or date. Popular slots such as Friday evening departures and Sunday evening returns are often excluded
- Sale fares typically carry restrictions on changes and refunds, so review the fare rules before purchasing
- Return legs may not be priced at the same level, so compare the total round-trip cost
- Confirm your passport validity and current entry requirements for Korea, including K-ETA, before travel
- Book via the Eastar Jet official website. Details and booking link: https://www.traicy.com/link/ZE
Summary
With fares from 2,000 yen one way and 15 kg of checked baggage included, this Eastar Jet promotion offers strong value.
