International Terminal

5–7 minutes on foot separates International from Domestic at PUS

Gimhae’s International Terminal handles Air Busan, Asiana, Jeju Air, Jin Air, and Korean Air flights, in a compact building that feels more like a regional hub than a major gateway. Arrivals here go straight into immigration and customs on one level, then out to landside where you exit the building to reach the Domestic Terminal in about 5–7 minutes on foot or via a short free shuttle ride.

International arrivals always clear formalities in this terminal, even on the special Incheon–Busan “international” sectors that run as through flights. FlyerTalk regulars point out that you must pick up checked bags from the International carousel, pass customs, and then walk or shuttle over to Domestic to re-check; there is no sterile transfer or through-checked international-to-domestic setup at PUS, so build that into your connection time.

For timing, most travellers report immigration plus customs in the International building taking around 20–40 minutes, depending on how many Air Busan and Korean Air flights land together. Experienced flyers on Korean routes suggest planning enough buffer to collect luggage and walk to Domestic rather than trusting minimum connection times; a safe rule of thumb is to assume 60–75 minutes from gate arrival in International to bag drop at Domestic check-in if you have checked luggage.

Landside in the International Terminal, the main food option sits on the upper level as a small food court directly above the check-in area. A TripAdvisor review calls out decent quality food and fast service here, which lines up with the “good Korean food” comment from a SleepingInAirports user, but options are limited compared with larger airports, and prices trend slightly higher than in central Busan for similar dishes.

There are no well-documented branded restaurants or retail chains tied to specific gate numbers in this terminal, so treat the upper-level food court and a few scattered kiosks as your core pre-flight supply stop. Expect standard Korean basics like bibimbap and noodle dishes plus quick fried items more than global chains, and plan to buy water and snacks before security if you want particular brands or quantities for a budget LCC flight on Air Busan or Jeju Air.

Airside, facilities are sparse and feel very low-cost-carrier, especially near Air Busan and Jin Air departures. Seating near the gates fills quickly at peak times when several narrowbody flights board at once, and travellers with large checked bags echo SleepingInAirports complaints about the layout being awkward, with limited space to stage luggage near the smaller gate areas and restrooms pushed a short walk away from some holding rooms.

The International Terminal has three lounges: the Air Busan Lounge, Sky Hub Lounge, and N Sky Hub Lounge, all located airside past security in the departures level. Access rules vary, but Sky Hub and N Sky Hub typically serve Priority Pass and pay-in customers, while the Air Busan Lounge mainly handles status and premium-fare passengers; food is basic but often includes simple hot Korean dishes and drinks that easily beat the gate areas for comfort during a delay.

Experiences with staff here are mixed: multiple reviewers praise general airport staff as polite and helpful, while one TripAdvisor user singled out the International Terminal tourist information center as “super rude, unfriendly.” If you need help with transfers or onward buses and trains, you might have better luck asking airline desks near the check-in rows of Air Busan or Korean Air instead of relying solely on that information counter.

One key operational quirk: PUS does not run 24 hours, and Korea Travel Guide posters warn that the airport, including the International Terminal, closes overnight. That means no sleeping in the public areas after late-night arrivals and no ultra-early check-in at 02:00 or 03:00; if you land close to midnight and fly out the next morning, you need a hotel in town or near the airport rather than a bench in the terminal.

Regulars on FlyerTalk and in Korea travel groups tend to avoid the very last departures and first-bank morning flights from Gimhae International when they have a choice, preferring mid-morning or afternoon departures. Their logic is simple: you get predictable airport opening hours, shorter lines at security for smaller banks of Air Busan and Asiana flights, and less stress if you are walking that 5–7 minutes over from Domestic with luggage.

Tip: if you are connecting from an international arrival in this terminal to a domestic flight at PUS, plan at least 90 minutes between scheduled arrival and domestic departure, then head straight from baggage claim out the front, follow the clearly signed pedestrian route to the Domestic Terminal, and check in again before thinking about food or coffee.
