Korean Air Adds 20 Jeju Flights; Eastar Adds 434 for Holidays

Three-Line Briefing

• Korean Air will deploy 20 mileage-special flights (about 3,160 seats) on the Gimpo–Jeju route for the Chuseok, National Foundation Day and Hangul Day holidays.
• Eastar Jet is adding 434 flights across five international and domestic routes from August through next month, supplying 82,000 seats in total. Of these, 32 additional flights will operate on the Gimpo–Jeju route from the 19th of this month through the 11th of next month.
• According to Agoda data, searches for domestic destinations during the Chuseok holiday rose 160% from two weeks before the holiday, while searches for overseas destinations increased 38%.

Where Press-Release Numbers Diverge From Actual Revenue

The 20 flights and 3,160 seats announced by Korean Air are mileage-special flights. Because seats are filled with members’ accumulated miles rather than ordinary paid tickets, an increase in flight numbers does not immediately translate into higher cash revenue. Korean Air operated 14 mileage-special flights during the previous Lunar New Year holiday and 20 during this year’s summer vacation season. This latest batch is the same scale as the summer program, looking less like an expansion for new demand than a seat-management tool the airline has repeatedly used during peak seasons.

Eastar Jet’s additional 434 flights and 82,000 seats are different in nature. A low-cost carrier’s (LCC) capacity increase assumes paid-seat sales, so if load factors hold up, more flights translate directly into higher revenue. The concentration of added service on Japan and Taiwan routes—144 flights each on Incheon–Tokyo and Incheon–Fukuoka, 58 on Busan–Fukuoka and 56 on Busan–Taipei—indicates that peak-season demand is gravitating toward short-haul destinations suitable for brief stays. An airline-industry official said, “With holidays such as Chuseok lined up, travel demand is expected to concentrate on short-haul international and Jeju routes,” adding that “airlines are flexibly adjusting capacity during periods of concentrated demand.”

Reading the Numbers in Context

The 2,551,261 passengers who used Cheongju Airport in the first half of this year, up 23.4% from the same period a year earlier, show the backdrop to this capacity race. Travel demand once concentrated at airports in the Seoul metropolitan area is spreading to regional hub airports, giving airlines more avenues to generate additional revenue beyond competition for Gimpo and Incheon slots. However, these materials alone cannot confirm whether the growth rate will carry over into the Chuseok peak season.

Agoda’s search growth figures—160% for domestic destinations and 38% for overseas destinations—tell a similar story. Searches indicate interest, not confirmed bookings. If the increase in searches converts into actual reservations, Eastar Jet’s 82,000 added seats should be filled as planned; if the conversion rate from searches to bookings is low, the added capacity could remain excess supply.

Potential Beneficiaries and Losers

• Korean Air — The 20 Gimpo–Jeju mileage-special flights are a recurring tool for domestic seat rotation and mileage redemption, continuing the scale and pattern of special-flight operations during the Lunar New Year and summer peak seasons.
• Eastar Jet — Adding 434 international and domestic flights and expanding supply by 82,000 seats is directly tied to higher paid-seat sales; if load factors remain stable, it should lead to revenue growth.

Risk Check

• The conversion rate between increased searches and actual bookings and load factors cannot be confirmed from these materials.
• Exact operating dates and ticket prices for the added flights were not disclosed, so the impact of higher flight counts on individual fares cannot be determined.
• The impact of these additions on each airline’s overall revenue and earnings has not been disclosed. It can only be assessed through domestic and Japan-route revenue and load-factor metrics in the next quarterly earnings release.
• Korean Air’s mileage-special flights move independently of paid revenue, so interpreting the increase in flight numbers as an immediate signal of improved earnings could lead to a wrong conclusion.

Bottom Line

These holiday capacity increases extend the supply adjustments airlines repeat every peak season. For revenue, the paid-seat expansion by an LCC such as Eastar Jet is a more directly connected indicator than Korean Air’s mileage-special flights. Until the next peak-season earnings report confirms that higher search volumes translated into actual load factors, it is too early to say whether this capacity increase reflects new demand or a seasonal repeat.
