South Korean Airlines Surpass Japanese Rivals on Korea-Japan Routes

South Korean Airlines Dominate Flight Capacity to Japan: A Comprehensive Overview

South Korean airlines have established remarkable dominance in the aviation market between South Korea and Japan, capturing an impressive 92% of flight capacity. According to December 2024 data from Cirium, this dominance translates to a staggering 1.3 million scheduled seats connecting these two neighboring countries, which are each other’s largest aviation markets.

South Korean Airlines’ Stronghold on Japan Routes

In stark contrast, Japanese carriers account for just 7% of the available seats, with Ethiopian Airlines contributing a mere 1% through its fifth-freedom flight between Incheon (ICN) and Tokyo Narita (NRT). The competitive landscape features 16 airlines in total, including 10 from South Korea, showcasing the significant influence of South Korean carriers.

Korean Air (KE), Asiana Airlines (OZ), and Jeju Air (7C) are the leading players in terms of total seat capacity, effectively outpacing Japanese airlines such as Peach Aviation (MM), All Nippon Airways (ANA), and Japan Airlines (JL).

Impact of the Korean Air and Asiana Airlines Merger

The anticipated merger between Korean Air and Asiana Airlines is poised to dramatically reshape the aviation market. Once finalized, the merged entity will control 32% of the total seat capacity between South Korea and Japan, with over 830,000 seats available. When considering subsidiaries like Jin Air, AIR BUSAN, and Air Seoul, the Korean Air group will dominate with a striking 60% of all available seats.

Currently, South Korean airlines maintain exclusive control over 46 of the 50 routes connecting the two nations. Competition primarily exists on major routes between metropolitan areas, including Gimpo-Haneda, Incheon-Haneda, Incheon-Narita, and Incheon-Kansai. Even on these routes, South Korean carriers hold a commanding presence, boasting up to 90% capacity on the Incheon-Narita and Incheon-Kansai routes.

A Shift in South Korea’s Aviation Landscape

The impending merger is expected to enhance South Korea’s standing as a top 10 global aviation market. This consolidation will reduce the number of domestic carriers from 10 to 7, concentrating market power among fewer players within the international airline sector. Cirium’s December 2024 schedules indicate that South Korean airlines currently control 70% of international seats, leaving foreign carriers with the remaining 30%.

According to aviation analyst Pang Yee Huat, the merger will elevate the combined market share of Korean Air and Jin Air to 49% of South Korea’s international seat capacity. Moreover, the merger will include Air Busan and Air Seoul, reinforcing the creation of more robust competitive entities within South Korea’s aviation landscape.

While South Korean airlines dominate, foreign carriers still maintain a notable presence, with 75 international airlines currently operating routes in South Korea. Leading foreign operators such as VietJet Air, China Eastern Airlines, China Southern Airlines, Vietnam Airlines, and Air China each control between 1-3% of seat capacity. To sustain market competition, South Korea’s aviation authorities are now actively seeking to enhance foreign airline participation.
