Southeast Asia’s aviation market continues its strong recovery, posting a 4.3% growth in overall capacity to 50.4 million seats in November 2025, compared to the same period last year. Data released by OAG highlights robust international growth and exceptional expansion by Malaysian carriers.
AirAsia maintains its dominance as the region’s largest airline, scheduling 2.8 million seats this month, marking a substantial 13.3% increase from November 2024.
However, Malaysia Airlines (MAS) recorded the fastest rate of growth, boosting its total capacity by an impressive 28.9% to 1.5 million seats. This rapid expansion was fueled by a significant 47% surge in domestic capacity, alongside notable growth in key international markets, including Australia, Indonesia, and Thailand.
Conversely, Lion Air saw the steepest capacity reduction among the top 10, cutting 8.4% of its seats, resulting in 221,000 fewer seats compared to November 2024.
Singapore Changi Airport (SIN) remains the busiest hub, with 3.5 million seats scheduled, despite a slight 0.4% reduction in capacity year-over-year.

Meanwhile, Denpasar-Bali (DPS) saw the most significant decline among the top 10, with capacity decreasing by 3.1%.
