Aviation – South Korea Air Travel Industry Faces Steep Monthly Decline
Aviation – South Korea’s aviation industry recorded a significant downturn in April as rising operational expenses and weaker travel demand weighed heavily on airline activity. Official figures released on Monday showed that the sector experienced its sharpest monthly contraction in more than four years, highlighting the growing challenges facing carriers across the country.

Sharp Fall in Aviation Output
According to data published by the government’s statistics authorities, the aviation production index dropped to 468.5 in April. This represented a 13.5 percent decline compared with the previous month and marked the steepest month-to-month decrease since December 2021.
The decline reflects mounting pressure on airlines as increased fuel-related costs have translated into higher expenses for travelers. Industry observers noted that the sudden rise in surcharges discouraged a portion of passengers from booking flights, contributing to the weaker performance across the sector.
Passenger Transport Activity Weakens
Air passenger transport services also registered a notable decline during the same period. Output related to passenger transportation fell by 14 percent from March levels, matching the most severe monthly drop seen since the end of 2021.
Government analysts linked the slowdown primarily to reduced consumer demand. Higher ticket costs, driven largely by increased fuel charges, have prompted some travelers to postpone or reconsider international travel plans.
Fuel Surcharges Rise Amid Global Tensions
A major factor behind the increased travel costs has been the continued instability in the Middle East, which has pushed up fuel prices globally. Airlines have responded by raising fuel surcharges to offset growing operating expenses.
Korean Air, South Korea’s largest full-service airline, significantly increased international one-way fuel surcharges for April. The additional charges ranged from 42,000 won to 303,000 won, compared with a range of 13,500 won to 99,000 won in March.
The higher surcharge levels were influenced by rising jet fuel prices linked to the Mean of Platts Singapore (MOPS), a widely used benchmark for refined petroleum products in the Asia-Pacific region. Between March 16 and April 15, the benchmark averaged 214.71 dollars per barrel, placing airline fuel surcharges in the highest pricing category.
Airlines Adjust Operations to Control Costs
Faced with escalating fuel expenses and softer passenger demand, several South Korean carriers have begun implementing measures aimed at reducing financial pressure.
Low-cost airlines have trimmed flight schedules, particularly on international routes, while also introducing temporary cost-saving initiatives. Some companies have offered unpaid leave programs and adopted other emergency management strategies to maintain operational stability during the downturn.
Jeju Air Cuts International Services
Among the airlines taking action is Jeju Air, the country’s largest budget carrier. The airline has reduced nearly 200 round-trip international flights during May and June, representing about 4 percent of its overall operations.
The affected routes include services connecting Incheon with destinations such as Bangkok, Singapore, Da Nang, and Phu Quoc. In addition, the carrier temporarily suspended flights to Vientiane for a two-month period beginning in late April.
Industry experts believe airlines may continue adjusting schedules if fuel costs remain elevated and travel demand does not recover in the coming months. The sector’s performance will likely depend on future developments in global energy markets and the pace at which consumer confidence in international travel returns
