Sale Highlights
Kumamoto–Busan Is the Cheapest at ¥1,900
The lowest fare in this sale is ¥1,900 from Kumamoto to Busan. Fukuoka to Busan, also from Kyushu, costs just ¥2,500. Busan is close to Kyushu, so it works well for a short weekend or long-weekend trip. All five Busan routes are priced under ¥5,000.
15 kg Checked Baggage Included
Low-cost carriers often charge extra for checked bags on promotional fares. This sale fare, however, includes 15 kg of checked baggage. Coats and sweaters can make winter luggage bulky, so a built-in baggage allowance is a real advantage. If your bags may exceed 15 kg, check the official website when booking to see how excess baggage is handled.
Travel Period Covers Christmas and the New Year
The travel period runs from December 1 to January 31 of the following year. If you’re planning a Christmas trip to Seoul or a Korea getaway over the New Year holidays, you can lock in flights early. Demand is high during peak season, however, and seats at the lowest fare may be limited to certain flights and dates. Check availability and fares for your preferred dates as soon as possible.
Compare Seoul and Busan from the Same Departure City
Four airports have sale fares to both Seoul/Incheon and Busan: Fukuoka, Osaka/Kansai, Okinawa/Naha and Sapporo/Chitose. From Osaka/Kansai, for example, the fare is ¥3,000 to Seoul/Incheon and ¥2,800 to Busan. From Sapporo/Chitose, it’s ¥7,100 to Seoul/Incheon and ¥4,800 to Busan. The lowest fare from the same city varies by destination. Kagoshima is included only for Seoul/Incheon (¥6,000), and Kumamoto only for Busan (¥1,900). Compare the options against your travel plans and budget.
