Foreign tourists spread across Korea as regional airports hit 20% share for first time

One in five foreign visitors who flew into South Korea in the first half of this year arrived through a regional airport — a milestone signaling that the quantitative growth of provincial gateways is now well underway. Yet structural weaknesses persist: many arrivals bypass the regions they land in and head straight to Greater Seoul, while per-capita spending by those who do stay is declining. Analysts say the key to a sustainable regional tourism ecosystem lies not in adding more flight routes but in strategies that extend visitors' time in the regions and drive high-value spending on accommodation, medical services and dining.

Data released by the Korea Tourism Organization at its second "Tourism Data Seminar" show that about 9.46 million foreign visitors arrived by air in the first half of 2026, up 21.7 percent from the same period a year earlier. Of those, about 1.96 million entered through four major regional airports — Cheongju, Daegu, Gimhae and Jeju — a 42.1 percent year-on-year increase. The regional airports' share of all air arrivals climbed from 16.6 percent in the first half of 2024 to 17.8 percent in the first half of 2025 and then to a record 20.7 percent in the first half of 2026, meaning one in five foreign air travelers now uses a regional gateway.

For the January-to-July period, total foreign arrivals reached about 12.8 million, up 21.3 percent year on year, with regional airport arrivals reaching about 2.38 million — a 40.0 percent increase that outpaced the national average. By country of origin, China retained its top position with about 3.99 million visitors, up 28 percent, while Taiwan posted about 1.41 million, up 33 percent, and Europe added about 870,000, up 20 percent — a diversified source-market structure that underpins the regional airports' growth.

Low-cost carriers drove much of the surge. In the first half of 2026, LCCs accounted for 97.5 percent of flights at Cheongju, 85.1 percent at Daegu, 79.9 percent at Gimhae and 70.7 percent at Jeju. At Cheongju, LCC departures rose 44.7 percent year on year, helping push foreign arrivals up 109.1 percent. Gimhae, up 46.6 percent, and Jeju, up 37.3 percent, also posted strong gains on the back of expanded LCC capacity.

Foreign tourist spending nationwide also surged. In the January-to-July period, visitors spent 12.09 trillion won ($8.76 billion), up 48.0 percent from the same period a year earlier. Spending in regions outside Greater Seoul grew even faster, rising 56.9 percent — a sign that the influx through regional airports is translating into genuine local consumption rather than mere transit.

Chinese visitors led the spending surge, with outlays reaching 2.6 trillion won, up 178.0 percent. Both transaction volume and per-transaction amounts expanded, driven by a growing share of high-ticket purchases such as watches, jewelry and dermatology procedures. Taiwanese visitors also crossed the 1 trillion won mark, up 46 percent, and their share of spending outside Greater Seoul reached 32.0 percent — the highest of any major source market — reflecting a deepening pattern of regionally dispersed consumption.

At the airport level, however, the picture diverges sharply. Korea Tourism Organization data show that while Cheongju airport's arrivals jumped 109.1 percent year on year and total spending in North Chungcheong Province rose 29.2 percent, average daily in-province spending per arrival fell 38.2 percent to 60,238 won. Daegu airport told the opposite story: arrivals grew just 2.6 percent, yet average daily in-region spending per visitor rose 9.9 percent to 255,355 won. The contrast illustrates how differently visitors behave — and spend — once they leave the terminal.

Movement-tracking data reveal wide gaps in how much each regional airport benefits its surrounding area. In the first half of 2026, only 40.5 percent of foreign arrivals at Cheongju airport stayed within North Chungcheong Province, while 34.5 percent traveled directly to Greater Seoul. The remaining quarter dispersed to adjacent provinces — South Chungcheong Province (12.5 percent), Daejeon (3.4 percent), North Gyeongsang Province (2.0 percent) and Sejong (1.6 percent).

Daegu airport showed a starkly different pattern: 53.8 percent of arrivals stayed in the city, and when nearby North Gyeongsang Province (18.9 percent) and Busan (10.7 percent) are included, the Daegu–North Gyeongsang corridor retained 72.7 percent of arrivals. Only 8.5 percent left for Greater Seoul. Gimhae airport was similarly self-contained, with 50.2 percent of arrivals staying in Busan and 47.9 percent dispersing to other parts of the Yeongnam region, leaving a Seoul outflow of just 1.9 percent. Jeju airport retained 93.8 percent of arrivals on the island.

Tourism industry observers describe Cheongju airport as functioning less as a hub for Chungcheong region tourism and more as a back-door entry point to Greater Seoul. Spending data from the first half of 2026 show that general dining (30.6 percent) and large shopping malls (27.1 percent) dominated consumption at Cheongju, while the share going to medical tourism — a high-value category — fell from 18.1 percent in the first half of 2025 to 8.4 percent in the first half of 2026. Although independent travelers in their 20s (38.7 percent of arrivals) and women (64.3 percent) are increasingly choosing Cheongju, the airport lacks the destination-worthy local content and transit connections needed to keep them. Urgent priorities identified include linking Cheongju to KTX Osong Station and developing region-wide food and beauty itineraries tailored to these visitor segments.

The Taiwan inbound market is widely cited as a benchmark for developing regional airports. Taiwan is unusual in that group tours booked through traditional travel agencies (40.6 percent) and independent travelers (57.8 percent) coexist in roughly equal measure. In 2025, about 1.89 million Taiwanese visited South Korea — a record high.

The Korea Tourism Organization's Taipei office pursued a deliberate geographic expansion strategy: starting with Busan-focused marketing in 2023, broadening to the southern coastal belt in 2024, then covering seven cities and provinces across the Yeongnam and Honam regions under a "Year of Southern Tourism" campaign in 2025, and shifting focus to the Chungcheong and Gangwon Province regions under a "Year of Central Tourism" campaign in 2026. Working with seven local governments, the office developed 21 curated itineraries and used them to design Taiwan-exclusive tour products, supporting promotional campaigns that generated 360 dedicated packages and attracted 70,716 visitors in 2025 alone. In South Gyeongsang Province, a traditional fire-flower festival in Haman was packaged as a foreign-visitor-only event that drove overnight stays among group tourists, and a popular Taiwanese variety program filmed on location in the central region helped raise awareness.

The targeted marketing produced a measurable shift in how Taiwanese visitors enter the country. The share arriving through Greater Seoul airports — Incheon and Gimpo — fell from 64.6 percent in 2019 to 48.2 percent in the first half of 2026, dropping below 50 percent for the first time. Gimhae airport's share rose from 19.1 percent in 2019 to 32.8 percent in the first half of 2026, a gain of 13.7 percentage points, while Jeju airport's share (13.3 percent) and Cheongju airport's share (2.4 percent) each roughly tripled and octupled, respectively.

Experts agree that the ultimate goal for regional airports should be to become hubs that generate overnight stays and high-value spending. The challenge, they say, is to design experiences that convert purpose-driven visits — concerts, sporting events — into extended stays.

Total foreign overnight stays nationwide rose 29.0 percent over the past three years, with the share outside Greater Seoul expanding to 43.0 percent. The effect of major K-pop concert weeks is particularly striking: foreign accommodation bookings during those weeks ran 6.2 times higher than normal, and bookings near regional professional baseball stadiums on game days rose 20.5 percent — 4.2 times the 4.9 percent increase recorded in Greater Seoul. Industry analysts point to bundled products such as Changwon's baseball-ticket tour pass and Gwangju's rail-accommodation-baseball package as models for converting a single-purpose visit into a multi-night stay.

The full analysis and the second issue of the Korea Tourism Organization's research note are available on the Korea Tourism Data Lab. The organization plans to hold its third seminar in November, where the focus will be on the fast-growing medical tourism market and its intersection with K-beauty and wellness trends.

Korea Tourism Organization President Park Sung-hyuk said regional airports, local destinations and K-content are increasingly converting into real visitor demand, making it essential to read the data accurately and find solutions that work on the ground. "We will expand opportunities to generate quality data and share insights with the industry and academia, fulfilling our role as a tourism policy partner that delivers tangible benefits to local communities," Park said.
