The aviation industry in the Asia-Pacific region continues to lead global short-haul travel, with the Jeju–Seoul route in South Korea ranking among the busiest worldwide in 2025. Offering 14.4 million seats, this corridor remains a vital link for leisure and business travelers, despite some recovery lagging by 17% from pre-pandemic levels.
This route exemplifies the region's extensive reliance on domestic air connectivity, driven by Jeju Island’s status as a primary tourism destination. Operated by seven airlines, the route's high flight frequency underscores its essential role despite broader sector challenges.
Regional Dominance in Short-Haul Routes
Analysis confirms that nine of the top ten busiest routes globally are located in Asia-Pacific, with Japanese domestic corridors like Sapporo–Tokyo and Fukuoka–Tokyo securing the following positions. This trend reflects high population density, limited land links, and a robust domestic tourism industry, all fostering sustained high-frequency air travel.
International routes such as Hong Kong–Taipei, with 6.8 million seats, along with Jeddah–Riyadh in Saudi Arabia and Melbourne–Sydney in Australia, highlight the region’s diverse connectivity priorities. The data demonstrates resilience in the face of global challenges, showing how short-haul, regional routes are central to the ongoing recovery and growth of international aviation.
These findings confirm that Asia-Pacific remains at the forefront of global aviation, with high-density, regional flights critical to connecting major cities and supporting economic activity across the region.
