Flights to Busan: The Complete Guide

Busan is South Korea’s second-largest city and its primary maritime gateway. Most travelers arriving on flights to Busan land at Gimhae International Airport (PUS). Located on the western edge of the city, Gimhae handles a high volume of domestic traffic from Seoul and direct regional flights from across Asia. While it is smaller than Seoul’s Incheon Airport, it offers a much faster entry point to the southern provinces and the coastal districts of Haeunda and Gwangalli. Recently, Busan has expanded its international reach, making it easier to skip the bus or train ride from Seoul and fly directly into the city.

Which airport should you fly into?

When searching for flights to Busan, you have one primary option for commercial air travel within the city limits, plus a secondary long-haul alternative.

• Gimhae International Airport (PUS): This is the main airport for Busan. It is approximately 15 kilometers (about 9 miles) west of the city center. It handles almost all international and domestic traffic into the region.
• Incheon International Airport (ICN): Located near Seoul, this is Korea’s primary international hub. If you cannot find a direct flight to PUS from outside Asia, you will likely fly here and take a high-speed KTX train or a domestic transfer to Busan.
• Ulsan Airport (USN): Located about 60 kilometers north of Busan. It is rarely used by tourists but serves as a backup for domestic travelers coming from other parts of Korea.

Best time to book flights to Busan

Timing your booking is critical for securing the best rates. Data suggests that for international flights to Busan, the "sweet spot" is typically 10 to 12 weeks before your departure date. If you are flying domestically from within South Korea (such as from Seoul-Gimpo or Jeju), booking 3 to 5 weeks in advance usually yields the lowest prices.

Avoid booking last-minute during the summer peak (July and August) or around major Korean holidays like Chuseok (autumn) and Seollal (Lunar New Year). During these periods, prices spike significantly and availability disappears months in advance.

Cheapest months to fly to Busan

If your schedule is flexible, targeting the shoulder seasons will help you find the cheapest flights to Busan.

• Lowest Prices: Late February, March, and November. These months sit just outside the peak cherry blossom and autumn foliage seasons. The weather is cool, but airfare is at its annual low.
• Moderate Prices: April, May, September, and October. These are the most popular times due to mild weather, leading to mid-range pricing.
• Highest Prices: July and August. These are the hottest months and coincide with summer vacations. Expect to pay a premium for any seat during this window.

Direct flights vs connecting flights

Your departure point determines whether a direct flight is possible.

Direct Flights: Most direct flights to Busan originate from major Asian hubs. You can fly non-stop to PUS from cities like Tokyo, Osaka, Taipei, Bangkok, Da Nang, and Singapore. There are also frequent "bridge" flights from Seoul’s Gimpo Airport (GMP), which take about an hour.

Connecting Flights: If you are traveling from the United States, Europe, or the Middle East, you will almost certainly need a connection. The most common route is flying into Seoul (ICN) and then either transferring to a domestic flight to PUS or taking the KTX train. Other popular connection hubs for Busan include Tokyo (NRT/HND), Hong Kong (HKG), and Shanghai (PVG). Choosing a connection often results in lower fares than attempting a multi-city direct itinerary.

Best airlines flying to Busan

Several carriers dominate the routes into Gimhae International. These airlines offer a range of service levels from budget to full-service.

• Korean Air: The national flag carrier offers full-service domestic and international connections with a high frequency of flights from Seoul.
• Air Busan: A low-cost carrier based in Busan, offering the most extensive network of regional flights across East and Southeast Asia.
• Jeju Air: A major Korean budget airline that frequently offers some of the cheapest flights to Busan from regional neighbors.
• Asiana Airlines: A full-service carrier providing consistent domestic links and several key international routes into PUS.
• VietJet Air: Frequently provides the most affordable options for travelers coming from Southeast Asia, particularly Vietnam.

Getting from the airport to the city center

Gimhae International Airport is well-connected to the city via public and private transport.

• Busan-Gimhae Light Rail Transit: This is the most efficient way to reach the subway system. It connects the airport to Daejeo (Line 3) and Sasang (Line 2). The fare is approximately 1,300 to 2,000 KRW.
• Limousine Bus: These specialized shuttle buses run to major districts like Seomyeon, Haeundae, and Busan Station. They cost between 7,000 and 10,000 KRW. They are better for travelers with heavy luggage.
• Taxi: A taxi to Seomyeon (city center) takes about 30–40 minutes and costs roughly 20,000 to 30,000 KRW. A trip to Haeunda Beach can take an hour and cost 35,000 to 45,000 KRW depending on traffic.
• Rideshare: While standard Uber exists in Korea, it primarily functions as a hailing service for licensed "Uber Taxi" drivers. Prices are comparable to standard taxi meters.

Flight duration from major cities

Since Busan is located in East Asia, travel times vary heavily based on your starting continent.

• From Tokyo: 2 hours (Direct)
• From Hong Kong: 3.5 hours (Direct)
• From Singapore: 6 hours (Direct)
• From Sydney: 13–15 hours (1 stop)
• From London: 14–16 hours (1 stop)
• From Los Angeles: 14–16 hours (1 stop)
• From New York: 16–18 hours (1 stop)
• From Dubai: 12–14 hours (1 stop)

Tips for finding cheap flights to Busan

1. Fly into Seoul and take the train: Sometimes the cheapest flights to Busan aren't flights to Busan at all. Check the price of flying into Seoul (ICN) and adding a KTX train ticket (approx. $45 USD). This can often save you hundreds of dollars on long-haul routes.
2. Use Korean Budget Carriers: Look specifically at Air Busan, Jin Air, and Jeju Air. These airlines often don't appear on every Western flight aggregator but consistently offer the lowest regional fares.
3. Monitor "Golden Week" and Holidays: Avoid traveling during the first week of May (Golden Week in Japan and China) or the Mid-Autumn Festival. Prices in and out of PUS triple during these windows.
4. Mid-week Departures: Statistical data for PUS shows that flying on a Tuesday or Wednesday is consistently 15-20% cheaper than Friday or Sunday departures.
5. Set Price Alerts for PUS, not just ICN: Many travelers only track flights to Seoul. By setting a specific alert for PUS, you can catch flash sales from regional hubs like Singapore or Taipei that others might miss.
