Air Busan is a South Korean low-cost carrier based in Busan, with a network focused on domestic routes and short- to medium-haul destinations across Asia and the western Pacific. For travelers deciding whether to book, the most useful facts are its strong recent punctuality scores, Airbus fleet, low-cost service model, the January 2025 aircraft fire, and major ownership changes now underway.
Quick Answer
Air Busan remains a reasonable low-cost option for many travelers. It earned A grades for both domestic and international operational reliability in South Korea’s 2025 airline-service evaluation. However, its January 2025 A321 fire, B safety grade for 2025, stricter battery rules, and coming integration with Jin Air are important factors to understand before booking.
Air Busan was founded in August 2007 as Busan International Air and was renamed Air Busan in February 2008, when Asiana Airlines invested in the carrier. Asiana remained Air Busan’s largest shareholder at the end of 2025, while Asiana itself is now controlled by Korean Air.
The airline’s main base is Gimhae International Airport in Busan. It operates an all-Airbus narrow-body fleet and focuses heavily on South Korea, Japan, China, Taiwan, Southeast Asia, and leisure destinations such as Guam and Saipan.

Safety and Maintenance
Air Busan operates under South Korea’s aviation-safety framework and oversight by the Ministry of Land, Infrastructure and Transport. Its aircraft are subject to the maintenance, inspection, crew-training, and operating requirements that apply to Korean commercial airlines.
A useful way to judge its current record is to look at both the airline’s overall operating history and the serious event that occurred in 2025 rather than relying on a blanket statement that any airline is simply “safe” or “unsafe.”
The January 2025 Air Busan Fire
Warning: On January 28, 2025, Air Busan flight BX391, an Airbus A321-200 preparing to depart Gimhae International Airport for Hong Kong, caught fire before takeoff. All 176 people aboard evacuated. Seven minor injuries were reported, and there were no fatalities.
The South Korean Aviation and Railway Accident Investigation Board published a preliminary investigation report covering aircraft HL7763. The initial report did not determine a final cause.
Investigators later reported evidence suggesting that a power bank found in the area where the fire began could have been involved. That was an interim finding, not a final determination of the accident’s complete cause.
The incident matters when evaluating Air Busan because it resulted in the loss of an aircraft and lowered the airline’s safety score in South Korea’s 2025 government service evaluation. Air Busan received a B in the safety category for that year.
At the same time, the evacuation was completed without fatalities, and Air Busan continued operating while introducing additional battery-handling and fire-safety measures.
Power Bank Rules After the Fire
Air Busan has since tightened its rules for lithium batteries. Under its current restricted-items policy, effective April 20, 2026, power banks, spare batteries, and e-cigarettes must not be placed in checked baggage or stored inside bags in overhead bins.
- Power banks must be kept on your person rather than in an overhead bag.
- Power-bank terminals must be protected against short circuits.
- Power banks are limited by capacity and quantity; airline approval is required for certain batteries over 100Wh.
- Using a power bank or charging it during the flight is prohibited.
- Electronic devices placed in an overhead bin must be completely powered off rather than left in sleep mode.
Pro Tip: Keep your power bank in a pocket or another location that complies with Air Busan’s current rules before boarding. Do not pack it deep inside your carry-on expecting to place that bag in the overhead bin.
Punctuality and On-Time Performance

Punctuality is one of Air Busan’s strongest measurable points. South Korea’s Ministry of Land, Infrastructure and Transport evaluates airline “operational reliability” using factors including schedule adherence and long delays.
In the government’s full-year 2025 evaluation, Air Busan earned an A grade for domestic operational reliability and an A grade for international operational reliability. Its international result was the highest grade earned by a Korean carrier in that category.
Air Busan earned A grades for both domestic and international operational reliability in South Korea’s 2025 airline-service evaluation.
That is stronger evidence than relying on a few individual flight-tracking results or traveler anecdotes. It does not mean every Air Busan flight will leave on time, since weather, congestion, aircraft rotation, crew availability, and airport conditions can still cause delays.
For a specific trip, check the historical performance of the exact flight number and leave extra connection time when traveling on separate tickets.
Customer Service and Satisfaction
The original article’s customer satisfaction, response-time, NPS, and retention percentages could not be verified from a reliable source. More useful information comes from South Korea’s 2025 airline-service evaluation, which included a large passenger survey and separate assessments of reliability, safety, and consumer protection.
| 2025 Metric | Verified Result |
| Domestic operational reliability | A |
| International operational reliability | A — highest among Korean carriers |
| Passenger satisfaction | 5.83 out of 7 |
| Government safety evaluation | B, affected by the January 2025 fire |
As with most low-cost airlines, service expectations should be different from those for a full-service carrier. Air Busan’s core product is transportation at a competitive fare, with many extras handled separately.
Its website and app support booking and flight management, although web or mobile check-in is not available to every passenger on every route. Air Busan states that web/mobile check-in is available for all domestic routes and for eligible international flights departing Korea and Japan, excluding Guam, with nationality and entry-rule restrictions applying in some cases.
What to Expect On Board
Air Busan is a low-cost carrier, so the ticket price does not necessarily include the same food, baggage, seat-selection, or flexibility benefits offered by a traditional full-service airline.
Its official in-flight service guide lists paid meals, beverages, Café Blue sales on eligible international routes, reading glasses, nursing covers, and in-flight duty-free service. Availability depends on the route and aircraft.
Travelers should therefore judge value based on the final trip price after adding any checked baggage, seat selection, meals, or other extras they need rather than comparing only the headline fare.
Baggage and Check-In Rules
Carry-On Baggage
Air Busan’s current free baggage rules allow one main carry-on weighing up to 10 kg (22 lb). The sum of its three dimensions must be no more than 115 cm, with individual side limits of 40 cm, 55 cm, and 20 cm including wheels and handles.
A small laptop bag or handbag meeting the airline’s additional-item requirements may also be permitted. Bags that exceed the allowance can be checked and may attract additional fees, particularly when dealt with at the boarding gate.
Checked Baggage
Checked baggage depends on the fare and route. Some promotional or “super special” fares do not include a standard checked-baggage allowance, while eligible regular or special fares may include 15 kg on many routes. Guam and Saipan have separate piece-based rules.
Note: Check the baggage allowance shown on your exact ticket before comparing Air Busan with another airline. A cheaper fare can stop being cheaper once checked baggage and seat fees are added.
Web and Mobile Check-In
Air Busan currently allows web/mobile check-in for all domestic routes. For international travel, it is available on eligible departures from Korea and Japan except Guam, with additional nationality and documentation restrictions.
International web/mobile check-in generally opens two days before departure and closes 1 hour 30 minutes before departure. Passengers who are not eligible must use the airport counter.
Fleet and Technology
Air Busan operates an Airbus A320-family fleet. According to the airline’s 2025 annual regulatory filing published in March 2026, it had 21 aircraft: five Airbus A320-200s, eight Airbus A321-200s, and eight Airbus A321neo aircraft.
The airline’s aircraft information page lists A320-200, A321-200, A321neo, and A321neo LR variants. The newer A321neo family offers improved fuel efficiency and, on Air Busan’s listed configurations, features such as seat power or USB connectivity on certain aircraft.
A newer aircraft type does not by itself establish an airline’s overall safety level, but the A320 family is a widely used commercial-aircraft platform, and Air Busan’s narrow-body fleet is well suited to its domestic and regional network.
Routes and Destinations

Air Busan’s network is centered on Busan, with additional operations from Seoul-area airports. Routes change by season and demand, so the airline’s live booking system should always be treated as the final authority for a particular date.
Domestic Routes
Air Busan’s currently published domestic network includes:
- Busan (Gimhae) ↔ Seoul (Gimpo)
- Busan ↔ Jeju
- Seoul (Gimpo) ↔ Jeju
- Ulsan ↔ Jeju
Incheon should not be treated as one of Air Busan’s listed domestic destinations. The airline uses Incheon for several international routes.
International Expansion
Air Busan’s current published route network includes destinations in Japan, mainland China, Hong Kong, Macao, Taiwan, Mongolia, Vietnam, Laos, Malaysia, the Philippines, Thailand, Indonesia, Guam, and Saipan.
Examples include Tokyo Narita, Osaka Kansai, Fukuoka, Sapporo, Qingdao, Xi’an, Hong Kong, Taipei, Da Nang, Hanoi, Bangkok, Cebu, Bohol, Bali, Guam, and Saipan. Some routes are seasonal or can be suspended or adjusted as airline schedules change.
Meeting Diverse Passenger Needs
The network is particularly useful for travelers beginning or ending a trip in Busan because many international flights operate directly from Gimhae rather than requiring a transfer through Seoul.
For passengers already in Seoul, the value proposition varies by route. Air Busan operates some international services from Incheon, but travelers should compare flight times and total trip cost with Jin Air, Jeju Air, T’way Air, Korean Air, Asiana, and foreign carriers serving the same market.
Air Busan, Asiana and the Jin Air Merger
Air Busan’s ownership situation is changing because of the Korean Air–Asiana consolidation. At the end of 2025, Asiana Airlines remained Air Busan’s largest shareholder with 41.89% of its shares, while Korean Air owned 63.88% of Asiana.
Korean Air and Asiana signed their formal merger agreement in May 2026. Korean Air says the integrated Korean Air is scheduled to launch on December 17, 2026.
Korean Air has separately said that its low-cost subsidiary Jin Air will ultimately be combined with Asiana’s low-cost carriers Air Busan and Air Seoul under a single Jin Air brand.
Note: The December 2026 date applies to the Korean Air–Asiana integration. Publicly available information reviewed for this guide does not establish an equally firm date for the separate Air Busan/Air Seoul/Jin Air brand consolidation. Until changes are formally implemented, check your booking with the operating airline shown on the ticket.
Reviews and Ratings
Passenger reviews of Air Busan vary by route and by what the traveler expects from a low-cost airline. Common positive themes include competitive fares, useful nonstop routes from Busan, and straightforward short-haul service. Complaints about low-cost carriers more generally often focus on baggage restrictions, paid extras, website usability, schedule changes, and limited support during disruptions.
Individual online reviews can be useful for learning what a particular airport or flight experience feels like, but they are a weak way to measure airline-wide reliability because review sites attract self-selected samples.
The more useful benchmark is South Korea’s government evaluation. For 2025, Air Busan’s passenger satisfaction score was 5.83 out of 7, while its domestic and international operational-reliability grades were both A.
The safety picture is more mixed: the airline’s government safety grade was B after the January 2025 fire. That event should not be ignored, but neither should it be treated as proof that every Air Busan flight or aircraft carries the same risk.
Is Air Busan a Reliable Airline?
On balance, Air Busan has several objective indicators in its favor. Its 2025 government operational-reliability ratings were strong, its international result led Korean carriers, it operates an Airbus A320-family fleet, and it maintains a useful regional network from Busan.
The main caution is the January 2025 aircraft fire. The incident destroyed an A321, caused seven minor injuries during the evacuation, contributed to a lower government safety grade, and led to tighter battery-handling policies. Travelers should understand that history rather than relying on a simplified “perfect safety record” claim.
Air Busan is likely to make the most sense when its schedule is convenient, the total fare remains competitive after baggage and seat fees, and you are comfortable with a typical low-cost service model.
You may prefer a full-service carrier when checked baggage, meals, schedule flexibility, lounge access, easier disruption handling, or mileage benefits matter enough to justify a higher fare.
Air Busan is also entering a period of corporate change. Its eventual integration with Jin Air could alter branding, flight numbers, route planning, booking systems, or loyalty arrangements. Travelers booking far ahead should therefore recheck their reservation and operating carrier as departure approaches.
