Asia’s aviation network is facing severe operational stress as widespread weather instability and cascading air traffic congestion disrupt major international routes. Heavy rainstorms, flooding conditions, and convective weather systems across parts of China have triggered large-scale scheduling breakdowns across multiple airports. As a result, airlines operating dense regional and long-haul networks have been forced to cancel 588 and delay 6,064 flights, creating significant travel uncertainty for passengers across key hubs in East and Southeast Asia. Major airports in Beijing, Kuala Lumpur, Tokyo, New Delhi, Istanbul, and Dubai are experiencing persistent delays as inbound and outbound traffic is repeatedly rerouted or held due to safety constraints. Airlines including Shenzhen Airlines, AirAsia, Batik Air, Garuda Indonesia, Korean Air, and Emirates are among those affected by the disruption wave. Consequently, travellers are facing extended waiting times, missed connections, and limited rebooking options as operational pressure continues to build across the regional aviation system.
The overwhelming majority of disruptions are concentrated in East and Southeast Asia on 16th June, where extreme rainfall and flooding conditions have pushed multiple aviation hubs into sustained disruption cycles.

The primary trigger behind the aviation disruption is extreme weather activity across China. Authorities confirmed that 20 rivers have exceeded warning levels, mainly small and medium-sized waterways, following continuous heavy rainfall across southern and northeastern regions.
This has created widespread waterlogging conditions affecting airport access roads, runway drainage systems, and ground handling infrastructure.

Southern China, particularly Guangdong Province and Guangxi Zhuang Autonomous Region, has been experiencing continuous rainstorms and severe convective weather.
Rainfall accumulation has reached 100–300 mm, with local peaks exceeding 600 mm. These conditions have significantly affected major aviation hubs such as Guangzhou, Shenzhen, and nearby secondary airports.
China’s meteorological authorities escalated alerts in response to worsening conditions:
These escalations directly impacted airport operations, forcing capacity reductions, rerouting, and extended holding patterns.
China represents the most severely impacted country in this dataset, with multiple mega-hubs reporting extreme congestion:
Secondary airports across Chengdu, Chongqing, Kunming, Nanjing, Wuhan, and Xi’an also report significant operational strain, indicating a nationwide network disruption rather than isolated incidents.
Beyond China, disruption has extended across key regional hubs:
These figures reflect ripple effects from disrupted air traffic flows originating in China’s congested airspace.
While not the epicentre, Middle Eastern hubs also show steady disruption accumulation:
These delays are largely linked to inbound scheduling disruptions from Asia-Pacific corridors.
Airlines operating dense China and intra-Asia networks are experiencing the highest disruption levels:
Regional carriers such as AirAsia, Batik Air, and Citilink also face moderate disruption due to network interconnectivity.
International carriers including Emirates, Etihad Airways, Japan Airlines, Korean Air, and Air India are experiencing secondary delays due to schedule knock-on effects.
Travellers across affected routes should take the following steps:
Given ongoing weather instability:
With flooding still affecting river systems and rainstorm alerts active across southern China, aviation operations are expected to remain unstable in the short term. The combination of waterlogged infrastructure, reduced airport capacity, and air traffic congestion suggests that delays will continue across China and neighbouring aviation networks until weather systems stabilise and river levels recede below warning thresholds.
