Busan aviation expansion is accelerating as travelers from Taiwan, China, the U.S., Japan, and Malaysia flock to South Korea’s second-largest city, yet limited direct flights at Gimhae International Airport (PUS) are straining capacity. Airlines including Korean Air, Air Busan, Starlux Airlines, AirAsia X, and Jin Air are launching and expanding routes from Taipei, Taichung, Osaka, Tokyo, and Kuala Lumpur to meet surging demand. The surge highlights both the city’s growing global tourism appeal and the urgent need for infrastructure and airline strategy adjustments to accommodate millions of foreign visitors and sustain Busan’s target of five million annual international tourists.

Cause of the Issue or Disruption

Busan’s popularity has surged, but direct international connectivity hasn’t kept pace. Although Gimhae International Airport serves as a gateway to Southeast Korea and handles international traffic to more than 40 destinations across 17 countries, capacity limits and crowded schedules constrain new flights. The airport is the fourth largest in South Korea with around 18.7 million annual passengers and continues to grow. International passenger traffic rose nearly 15 % in early 2025, reflecting rising demand for overseas travel centered on Busan. Despite this rise, most routes still focus on short‑ to medium‑haul flights.

Compounding the challenge, airlines are under pressure to expand service but face limited runway and terminal capacity, forcing carriers to sequence new routes carefully. As Busan tourism growth spreads beyond Northeast Asian markets, demand for long‑haul services — especially from the U.S. and Southeast Asia — is outpacing the airport’s ability to launch them at scale.

Airlines or Countries/Regions Affected

The Busan market is seeing activity from a broad mix of airlines and source regions. Several carriers are actively expanding flight networks out of PUS in 2026:

Major airlines involved in route expansion
• Air Busan — leading domestic and regional service and launching new routes such as Busan–Shizuoka (Japan) three times weekly.
• Jin Air — opening new routes to Taichung (Taiwan) five times weekly and Miyakojima (Japan).
• AirAsia X — launching four weekly flights to Kuala Lumpur (Malaysia).
• Starlux Airlines — adding service from Busan to Taichung (Taiwan).
• Jeju Air, T’Way Air, Eastar Jet — operate direct flights to major cities including Osaka and Sapporo.

Top source countries
• Taiwan — served by multiple airlines to Taipei.
• Japan — strong coverage to Osaka, Tokyo, Sapporo and Shizuoka.
• China — direct flights to Beijing and other cities.
• Malaysia — new AirAsia X service expands Southeast Asian footprint.
• Vietnam and Kazakhstan — emerging connections via Jin Air and Eastar Jet.

This diversity underlines how Busan’s international connectivity spans East, Southeast, and Central Asian regions.

Impact on Passengers

Passengers flying to and from Busan are experiencing both benefits and disruptions from the current expansion phase:

Real‑world effects
• More direct routes: Travelers from Taiwan, Japan and Malaysia now enjoy more non‑stop connections, reducing reliance on indirect travel via Seoul or Incheon.
• Capacity limitations: Some long‑haul and high‑demand slots remain scarce, causing peak‑season flight sellouts and higher fares.
• Route diversification: New services to lesser‑served cities such as Taichung and Shizuoka expand options beyond traditional links to Osaka and Taipei.
• Traveler behavior shift: Some passengers still choose to land in Seoul and take domestic connections due to limited long‑haul offerings from Busan.

Passengers now weigh direct flight availability against cost, time, and convenience, influencing overall travel patterns across East Asia.

Airline or Country/Industry Response

Both airlines and governments are adapting to meet the surge in demand:

Carrier strategies
• Air Busan is strengthening its Japan network and exploring charter services to capture seasonal leisure demand.
• Jin Air is aggressively launching routes to Taiwan and expanding in secondary Japanese markets.
• AirAsia X’s Kuala Lumpur link opens Southeast Asian inbound demand to Busan.

Government and airport efforts
• Korean aviation authorities and Busan city officials are incentivizing regional international flights to reduce congestion at Seoul airports and diversify point‑of‑entry tourism. Expansion of airport facilities and negotiation of bilateral air service agreements are part of longer‑term planning.
• Route support and tourism promotion programs aim to boost foreign visitor numbers while infrastructure catches up.

What Travelers Should Do

To make the most of the changing Busan aviation landscape, passengers should:

• Check flight schedules early — new routes have limited seats and may fill quickly, especially summer seasonal services.
• Compare carriers and airports — consider direct flights to Gimhae (PUS) when available, or Seoul entry with onward domestic connections.
• Book hotel and transport in advance — tourism growth is driving strong occupancy in Busan hotels and ground transport.
• Monitor airline policies — check baggage rules and cancellation policies for carriers such as Air Busan and Jin Air.
• Use official airport information — verify departure terminals and customs procedures at Gimhae International.
