India, China and Southeast Asia Forecast to Anchor Future Global Air Travel Demand

Asia is emerging as the engine of global aviation growth, with India, China and Southeast Asia forecast to account for eight of the world’s ten fastest-growing air travel markets between 2024 and 2044. The outlook is detailed in a new whitepaper released by Alton Aviation Consultancy ahead of the 2026 Singapore Airshow. According to the report, international traffic in the Asia-Pacific region grew by 8.0% in 2025, outpacing global revenue passenger kilometre (RPK) growth of 6.8%. Airlines across the region have launched more than 600 new routes since 2015, significantly improving access to underserved destinations and strengthening intra-regional connectivity. India is highlighted as one of the world’s fastest-growing aviation markets, underpinned by strong economic fundamentals and a rapidly expanding middle class. While China continues to play a dominant role in regional air travel demand, the report identifies Southeast Asia as an emerging growth engine, led by markets including Indonesia, Vietnam and the Philippines. Mabel Kwan, Managing Director in Alton’s Singapore office, said:“Asia’s air travel story is no longer just about China. The growth we’re seeing in South and Southeast Asia is broad-based. Airlines are responding with strategic moves, from entering new markets and renewing fleets to forging ambitious partnerships that reflect the region’s evolving competitive dynamics.” The whitepaper also identifies substantial near-term opportunities in currently unserved or underserved routes. The introduction of longer-range narrowbody aircraft is expected to enable new point-to-point services between secondary cities, supporting sustainable growth on routes previously unsuitable for widebody operations. Beyond passenger traffic, the report underscores Asia-Pacific’s expanding role in the global air cargo market, with the region now accounting for approximately 40% of total freight demand. This reflects the growing importance of intra-Asia trade and Asia’s central position in global supply chains. Alton further notes a rising wave of airline consolidation across Asia, as carriers restructure in response to cost pressures and intensifying competition. While demand remains strong, margin challenges are driving operators to explore new business models aimed at long-term resilience. Adam Cowburn, Managing Director in Alton’s Singapore office, commented:“As competition intensifies and financial headwinds persist, consolidation has become a strategic necessity for many airlines in Asia. We’re seeing patterns that echo past restructuring cycles in North America and Europe. But in Asia, this shift is unfolding against a backdrop of continued traffic growth, creating a very different opportunity set.” To support sustained growth, governments and airport operators across the region are progressing large-scale aviation infrastructure programmes and deploying next-generation technologies to enhance capacity, operational efficiency and the overall passenger experience.
