Jeju Air Fills the Gap Left by Major Airline Mergers

Interline Agreement with Air Premia
Network Integration and Transfer Support at Incheon Airport
Capturing North American Demand Without Operating Own Flights

Jeju Air, the top domestic low-cost carrier (LCC), has unveiled an indirect strategy to open routes to North America without adding long-haul aircraft to its fleet. The company intends to overcome the structural limitations of LCCs—namely their focus on short-haul routes—through partnerships in an airline market reorganized by the consolidation of major carriers.

On July 27, Jeju Air and Air Premia announced that they will launch interline connection services starting from August 1. The two companies signed an interline agreement in early July, agreeing to link their route networks and support passenger transfers at Incheon International Airport.

Starting next month, passengers arriving in Incheon from Japan or Vietnam on Jeju Air flights will be able to transfer to Air Premia's North American-bound flights without reclaiming their checked luggage. The cities covered by this connection are Los Angeles, New York, San Francisco, Honolulu, and Washington D.C., totaling five destinations. The reverse direction is also available. North American passengers flying into Incheon on Air Premia can continue their journeys on over 40 Jeju Air-operated international routes, including Japan, China, Taiwan, Singapore, Vietnam, Thailand, Mongolia, and Indonesia, as well as on domestic routes such as Incheon–Jeju.

An interline agreement enables airlines to sell separate segments they operate as a single ticket. Passengers do not need to purchase separate tickets from each airline. Airlines can expand their route networks without increasing their number of aircraft. This arrangement is what has enabled Jeju Air to add Pacific routes to its list of destinations.

Baggage services vary depending on the connecting segments. For journeys connecting international flights, baggage can be checked through from the originating airport to the final destination. For itineraries that include domestic flights, no baggage transfer service is provided. However, for routes involving the United States, Air Premia's free checked baggage policy applies equally to the entire journey—both outbound and return—conforming to international regulations.

With this agreement, Jeju Air now has interline partnerships with 21 airlines, including Air Canada, United Airlines, and Lufthansa Group, the highest number among domestic LCCs. The strategy appears to be to tap into transfer demand at Incheon Airport by transferring passengers accumulated on short-haul routes to long-haul partners.

Historically, Jeju Air has focused its fleet on short and medium-haul routes. Entering the long-haul market directly would require acquiring wide-body aircraft and expanding maintenance infrastructure, a significant burden. Interline agreements are a way to broaden the route network without such expenses. This effectively provides a route to capture North American demand without operating its own flights.

Air Premia is a hybrid airline that has expanded its North American routes using mid- and large-sized aircraft. As long-haul route rights and slots returned during the merger of major airlines were redistributed, Air Premia increased its North America services. Now, with Jeju Air's short-haul Asian network complementing this, the two companies are able to fill in each other's weaker segments.

A Jeju Air spokesperson stated, "By leveraging the combined route networks of both airlines, we can maximize synergy and respond to the diverse travel needs of customers," adding, "We will continue to enhance transfer convenience and improve related services."

An Air Premia spokesperson commented, "Connecting Jeju Air's domestic and Asian network with Air Premia's North American routes will greatly improve passenger mobility," adding, "We will continue to expand collaborations with various airlines to further enhance travel convenience and broaden passenger choice."

Industry watchers predict that following the consolidation of major airlines, the competitive landscape for long-haul routes will change, leading to further alliances and partnerships among small and midsize carriers. Given the time and costs required to expand individual fleets, such network expansion through partnerships is expected to remain a practical alternative for the foreseeable future.
