Final Assessment: Airport construction restart, opening reset to 2035, industrial strategy execution clock unconnected
The official opening date for the Gadeokdo New Airport has been changed from December 2029 to the second half of 2035. The current project scale disclosed by Busan City includes a site area of approximately 6.67 million square meters and a total project cost of approximately 15.9 trillion won . Based on a construction period of 106 months, the Daewoo E&C consortium commenced the basic design for site preparation in March 2026. The commencement of the priority construction phase in the second half of 2026 marks the first hurdle in the current timetable. ( Busan Metropolitan City, Gadeokdo New Airport , Basic Design for Site Preparation )
The initial master plan proposed a 3,500m runway, 24-hour operation, a cargo terminal of 17,200㎡, a site for cargo-related facilities of 98,000㎡, an expansion site of 47,000㎡, and a site for aviation integrated logistics support facilities of 1.26 million㎡. The airport was designed as an integrated logistics hub combined with Busan New Port and the hinterland railway, rather than focusing on passenger facilities. ( Busan Metropolitan City )
Busan City has proposed Sea & Air integrated logistics, specialized e-commerce complexes, repackaging and remanufacturing, airport complex cities, regional hub airlines, and aviation professionals as its industrial directions. In 2026, it also commissioned a study on the revitalization of air logistics within the new airport zone and strategies for operational participation. A list of policies regarding post-airport industries exists. ( Busan Metropolitan City 2026 Work Plan )
However, an integrated industrial milestone has not been identified that includes air cargo targets, tenant contracts by company, airport complex city construction, port-airport transshipment times, regional airline cargo networks, and the recruitment of specialized personnel, all aligned with the 2035 opening. There is a time gap of at least five years between the existing integrated logistics and hinterland city plan, which was drawn up based on the premise of a 2029 opening, and the 2035 construction schedule.
The period from 2026 to 2029 has shifted from being the time for the airport's opening to a period for resetting the preconditions for industrial sites, transportation networks, companies, and logistics systems. If the industrial plan merely pushes back the opening date during this period, corporate investment and local manpower will be left on hold, while land and redevelopment costs will accumulate first. Although Busan envisioned industries for the post-Gadeokdo New Airport era, it is difficult to conclude that the implementation structure has been reorganized to align with the revised opening timeline.
The Gadeokdo New Airport was announced in the 2023 master plan with an opening date of December 2029 and a total project cost of 13.49 trillion won, but current public data from Busan City suggests an opening date of 2035 and a total project cost of approximately 15.9 trillion won. The site preparation work commenced with the basic design following two failed bids and a private contract procedure.
The project shifted from a structure centered on early opening to a long-term construction structure reflecting safety, quality, and a 106-month construction period. As the opening target was pushed back by more than five years, the base years for access transportation, hinterland cities, airlines, and industrial locations also changed.
However, an integrated schedule showing whether the base year for each linked project has been readjusted to 2035 has not been confirmed. If only the airport construction moves according to the new schedule for two to three years while the supporting industries remain stuck in existing plans and individual services, the time axis of the entire project becomes separated.
Although the Gadeokdo New Airport has entered the phase of resuming construction, the overall airport economy has not yet completed its schedule readjustment.
In 2023, the simultaneous operation of the port, airport, and railway "Tri-port" and the Airport Complex City was proposed, based on the premise of an opening in 2029. In 2026, the official target was changed to the second half of 2035 for the opening, and the Busan Metropolitan City government also began formulating its own early activation strategy. ( Busan Metropolitan City )
The time structure shifted from short-term preparations with three years remaining until the opening of the port to the establishment of long-term leading industries spanning approximately nine years. While land, corporate attraction, talent, logistics data, and air routes secured longer preparation periods, the waiting period between investment confirmation and revenue generation also increased.
No public portfolio has been identified regarding which projects among existing industrial strategies should be prioritized and which should be aligned with the opening date. If priorities for 2026–2029 remain unclear, development unrelated to the airport will proceed first, and investment in aviation-dependent industries will be postponed.
The delay in opening the port represents an increase in preparation time and uncertainty regarding industrial strategy; currently, Busan has secured the former but has failed to eliminate the latter.
Gadeokdo New Airport includes a 3,500m runway capable of 24-hour operation and the takeoff and landing of large cargo planes, a cargo terminal, and a 1.26 millionm complex logistics support site. The master plan incorporates a structure to convert maritime cargo to air cargo by connecting Busan New Port, the Airport Railroad, and access roads.
The economic impact of an airport shifts from passenger numbers and construction costs to air cargo, e-commerce, cold chain logistics, repackaging, remanufacturing, maintenance, finance, and insurance. Runways do not directly create industries but are transformed into industrial assets when time-sensitive cargo and corporate supply chains are present.
There is no up-to-date evidence linking air cargo demand by item, sea-to-air convertible volume, and contract intent by shipper in Busan, Ulsan, and Gyeongnam. If supply chain demand is not reflected in site planning for two to three years, complex logistics sites will shift to general warehouses and real estate development.
Although the facilities at Gadeokdo New Airport have been designed as a logistics hub, the cargo and companies that will actually drive the airport economy remain unconfirmed.
The master plan included a cargo terminal of 17,200 square meters, a site for cargo-related facilities of 98,000 square meters, and a future expansion site of 47,000 square meters. Busan City reviewed a strategy to revitalize air logistics in the new airport zone, which will serve as a logistics hub for the southern region by 2026.
Competition in air cargo is shifting from the scale of airport facilities to the stable securing of high-value-added cargo capable of covering freight costs, such as semiconductors, bio-products, fresh food, e-commerce, and emergency parts. Only a portion of Busan Port's large-scale container volume has the potential to be converted to air cargo.
Public data combining projected cargo volumes by item, freight rates, transshipment times, shipper intentions, and airline route plans is not available. If cargo routes and anchor shippers are not finalized for 2026–2029, the airport will continue to rely on passenger baggage and small cargo even after opening in 2035.
Although cargo facilities for Gadeokdo New Airport have been planned, it cannot be determined that an air cargo market exists yet.
Gadeokdo New Airport is adjacent to Busan New Port, and the master plan includes a 9.3 km access road and a 16.5 km airport railway connecting to the Busan New Port hinterland railway. Busan City has established the Tri-Port, connecting the port, airport, and railway, as the foundation for a global logistics hub.
While physical proximity exists, multimodal logistics operates when container handling, customs clearance, bonded transport, and aircraft loading are linked into a single reservation and responsibility system. The completion of the three facilities and integrated operation are separate stages.
Target transshipment times from ports to airports, integrated customs clearance procedures, operating entities, multimodal transport rates, and data standards are not confirmed in public data. If operational design lags behind facility design by 2 to 3 years, Sea & Air cargo will use existing transshipment airports even after railways and roads are completed.
Busan Triport exists as a spatial structure, but it is not yet formed as a logistics product.
Busan City has been developing an airport complex city and a complex logistics complex behind the Gadeokdo New Airport and has been pursuing the designation of an Economic Free Zone. In 2025, it proposed specialized industries for Sea & Air logistics and e-commerce in conjunction with the lifting of development restrictions on an area of approximately 5 million pyeong. ( Busan Metropolitan City )
The plan is to shift the airport hinterland from a logistics warehouse-centered model to an industrial city integrating manufacturing, processing, research, business, and residential areas. However, due to delays in the airport's opening, the supply of industrial land and the timing of companies' air access have become separated.
No milestones by 2035 linking the designation of the Free Economic Zone, reclamation, infrastructure, land supply, and the entry of anchor companies have been identified. If land supply proceeds ahead of industrial demand between 2026 and 2029, real estate expectations will preempt prices and locations over the airport economy.
While a spatial plan exists for the Gadeokdo Airport Complex City, evidence for industrial city occupancy and employment has not yet been established.
Busan City has included fostering a regional hub airline, strengthening the competitiveness of the air transport industry, and training aviation professionals in its 2026 work plan. This confirms the policy direction of expanding the Gadeokdo New Airport from an airport facility into a foundation for the regional aviation industry.
However, the regional airline's aircraft, route, and cargo transportation plans, the hiring scale for maintenance, operations, air traffic control, and logistics personnel, and parts and service supply contracts with Busan companies cannot be verified. Owning an airline is separate from owning an aviation industry supply chain.
If the capital and route bases of local airlines weaken during the nine-year preparation period leading up to the opening, slots at the new Gadeokdo Airport will be preempted by external airlines, and Busan companies will be limited to ground handling and services. Busan's aviation industry exists as a policy target, but it remains unformed as a supply chain for local companies.
The site preparation for the new Gadeokdo Airport has commenced its basic design, and Busan City is proceeding with services and projects related to air logistics, airport operations, the hinterland city, and hub airlines. We have passed the stage where the airport and industry were not perceived as separate issues.
However, a public system connecting the port opening date, transportation access, integrated city, air cargo, corporate attraction, and workforce training into a single Critical Path has not been identified. While schedules for individual projects exist, the overall industrial readiness is not assessed.
If each project is pursued independently between 2026 and 2029, the latest project will determine the start date of the entire airport economy. In Busan, while airport construction and industrial planning exist, the integrated industrial runtime has not yet been formed.
Busan City has repeatedly presented Sea & Air integrated logistics, e-commerce, repackaging and remanufacturing, an airport complex city, the aviation industry, and the Tri-port. The industrial direction, which does not limit the new airport to passenger demand, has expanded into various work plans.
However, the results of this transition into industry-specific anchor firms, investment commitments, land demand, employment, and freight contracts have not been confirmed. While strategic terminology has spread, the execution of capital by private enterprises remains unconfirmed.
If only services and plans are repeated for two to three years, corporate investment decisions will continue to be postponed due to the delay in the opening. While the industrial strategy for the Gadeokdo New Airport has spread within the administration, there is no evidence to conclude that it has spread to the corporate investment stage.
The demand for the Gadeokdo New Airport is not formed solely by Busan's consumption and industry, but relies on Ulsan's automobile and chemical industries, Gyeongnam's machinery, defense, aerospace, and shipbuilding industries, and Busan's port, fisheries, and e-commerce cargo. The 2026 Metropolitan Transport Plan includes multiple routes connecting the Gadeokdo New Airport with Ulsan and Changwon.
However, joint data comparing air cargo demand by item from companies in the Busan-Ulsan-Gyeongnam region, transit times to the airport, and the costs of using existing Incheon and Gimhae airports is not disclosed. There is a gap between the southern gateway airport and the actual industrial demand in the southern region.
If metropolitan transportation and cargo contracts for 2026–2029 remain a Busan-only plan, companies in Gyeongnam and Ulsan will maintain their existing networks utilizing metropolitan and overseas hub airports. Although the Gadeokdo New Airport has been designated as a joint infrastructure project for the Busan-Ulsan-Gyeongnam region, it remains unconfirmed as a joint industrial market.
12-1. Gadeokdo and Gangseo-gu — The Time Lag Between Airport Construction and the Industrial City
Basic design has entered the site preparation phase for the Gadeokdo New Airport, based on a construction period of 106 months and aiming for an opening in the second half of 2035. Gangseo-gu is home to a concentration of Busan New Port, the International Industrial Logistics City, Eco Delta City, and the planned site for the Airport Complex City.
However, the construction of the airport and the schedules for the designation of the economic free zone, reclamation, land supply, and corporate relocation in the hinterland city cannot be confirmed on a single timetable. The structure is such that the airport and the city operate as separate development projects.
If compensation and land planning are finalized before industrial demand within two to three years, location costs rise, and subsequent entry costs for air logistics companies also increase. Gangseo-gu has secured space for the airport economy, but the simultaneous development of industrial functions remains unconfirmed.
12-2. Busan New Port — Undemonstrated Sea & Air Transition
Busan Port handles over 24 million TEU annually and is located adjacent to the planned site of the new Gadeokdo Airport. Busan City has proposed a Sea & Air model that diverts port cargo to the airport to create logistics for repackaging, remanufacturing, and e-commerce.
However, the items, volumes, and shippers capable of being converted to air cargo among the current cargo at Busan New Port, as well as the results of actual trial transport, have not been confirmed. There is no evidence that large-scale container throughput will automatically convert into future air cargo demand.
If pilot cargo is not accumulated during the two to three years prior to opening, airlines and shippers will prioritize existing hubs with proven demand even in 2035. Busan New Port is a physical source for Sea & Air, but it remains undecided as a commercial multimodal logistics market.
Busan City announced that in 2026, the equity stake and participation amount of Busan companies in the Daewoo E&C consortium increased by 10.3 percentage points and 1.1189 trillion won, respectively, compared to the previous Hyundai E&C consortium proposal. This is evidence that the local allocation of airport construction costs has expanded.
However, participation in construction and participation in the aviation, logistics, maintenance, and data industries after the opening of the airport constitute different supply chains. The proportion of local company participation in the areas of technical design, smart airport systems, long-term operation, and maintenance has not been confirmed.
If local companies focus on civil engineering, materials, and construction between 2026 and 2029, revenue and employment will decrease after construction is completed, and recurring profits from airport operations will accrue to external companies. While the participation of local companies in construction has expanded, their transition to becoming suppliers in the airport industry remains unconfirmed.
The opening of the Gadeokdo New Airport has been pushed back from 2029 to 2035, and the total project cost has increased from approximately 13.49 trillion won to 15.9 trillion won. Due to the extension of the construction period, the waiting times for industry, real estate, transportation, and finance have also increased.
However, integrated evidence regarding the funding requirements, infrastructure maintenance costs, corporate withdrawals, land price risks, and resident compensation risks associated with the airport complex city due to the revised schedule has not been confirmed. Construction delay costs and industrial opportunity costs are separated.
Between 2026 and 2029, if industrial sites and transportation networks are positioned too far ahead of the airport, idle costs will be incurred; if they are too far behind, industrial operations will be delayed even after the airport opens. Once land use and supply chains are finalized, the costs of reorganizing around the airport industry will also skyrocket.
The irreversibility of the Gadeokdo New Airport lies not in the delay of its opening, but in the fact that the hinterland space becomes fixed to functions unrelated to the airport before the opening.

Airports begin operations on the day the runway opens, but industries decide on locations even before that. Airlines design routes, shippers change logistics contracts, companies build factories and warehouses, and personnel use the airport after accumulating qualifications and experience.
As the opening of Gadeokdo New Airport shifted from 2029 to 2035, post-airport industries did not automatically move six years later. Shippers and companies may enter into long-term contracts with other airports, ports, and logistics platforms during that period, and hinterland land may be preempted for other uses.
The delay in opening the airport extended the time for industrial preparation, but at the same time, it also gave competing cities time to secure customers and supply chains. Even if the facilities are completed in 2035, if companies, cargo, airlines, and personnel are already entrenched in other networks, the airport will exist but the airport economy will be delayed.
The industrial strategy following the Gadeokdo New Airport is not determined by plans that begin after the opening, but by whether cargo and companies arrived before the opening.
