Asia Pacific Aviation Connectivity in 2025

Observations from the Post-Pandemic Recovery

This white paper—independently developed by Deloitte based on air travel data provided by OAG—examines how international and domestic commercial aviation networks have evolved, both quantitatively and qualitatively, before and after the COVID-19 pandemic.

 

Through a data-driven analysis of international and domestic airport pairs in Asia Pacific, we uncover the deep structural shifts in the regional fabric of air transport that have taken place over the past 12 years. Our findings complement the extensive commentary that already exists on the impact of COVID-19 on overall passenger and cargo traffic levels and the airline competitive landscape by focusing specifically on the stunning rebalancing of air connectivity from international to domestic and its implications for the Asia Pacific region.

We begin this report with an overview of connectivity at a regional level, focusing on changes to international and domestic networks, and a commentary on the balance between low-cost carrier (LCC) and full-service carrier (FSC) penetration. We then narrow our analysis to a sub-regional level, covering Southeast Asia, Northeast Asia, Central Asia, South Asia, and Southwest Pacific individually; as well as the top gainers and losers at the individual market level. Each sub-region presents unique dynamics, such as Northeast Asia’s muted international reopening, South Asia’s explosive domestic growth, and Central Asia’s emergence as a strategic connector.

We then turn to connectivity shortfalls and identify the region’s unserved international routes by measuring transfer traffic between behind and beyond destinations that lack a direct nonstop service. Lastly, we conclude with strategic recommendations for airport operators, airlines, and policymakers — outlining how stakeholders can adapt to the new network realities through smarter capacity planning, targeted partnerships, and stronger alignment of their policy frameworks.

Southeast Asia highlights

Southeast Asia’s aviation industry is poised for robust growth, with its momentum fueled by a rising middle class and the region’s unique geography, which comprises numerous islands that make overland travel challenging.

Prior to the COVID-19 pandemic, Southeast Asia was one of the fastest-growing aviation markets globally, benefiting from rising middle-class demand, liberalized air services, and the rapid expansion of LCCs. Between 2013 and 2019, Southeast Asia saw a net gain in international airport pairs across several key markets, particularly with Northeast Asia (+378 pairs).

Southeast Asia air travel experienced a slow and uneven recovery from the COVID-19 pandemic. Between 2019 and 2025, the region lost 188 international airport pairs, revealing the depth of the pandemic's impact and the region’s heavy reliance on Northeast Asian travel demand—particularly from Mainland China. Connectivity with Northeast Asia fell sharply by 214 pairs, reversing much of the growth seen in the previous six years.

Intra-Southeast Asia connections declined slightly, losing six airport pairs between 2019 and 2025, and routes to Europe dropped by 14. Connectivity with the Southwest Pacific dropped by two connections, while Africa saw a modest gain of one. In contrast, there were small but meaningful increases in airport pairs to North America (+3), the Middle East (+3), Central Asia (+10), and South Asia (+29), signaling a gradual diversification of network strategies.

At the market level, the contrast between pre- and post-pandemic trends is stark. Between 2013 and 2019, all major Southeast Asian markets gained international connections—led by Thailand (+162), Vietnam (+98), and Cambodia (+65).

However, between 2019 and 2025, Thailand (–58), Cambodia (–52), the Philippines (–23), and Myanmar (–23) saw the largest declines. In contrast, Vietnam (+4), Lao PDR (+1), and Singapore and Brunei (–4) demonstrated greater resilience or stabilization, reflecting more balanced recovery trajectories.

While Southeast Asia's international aviation network grew significantly in the years leading up to the pandemic, much of that growth has since been erased—especially with Northeast Asia. Nonetheless, strategic gains in long-haul and emerging markets point to a slow but ongoing shift toward more diversified and resilient connectivity.
