Severe weather disrupts 6,961 flights across Asia’s major hubs

Disruption overview

Severe summer thunderstorms and airspace constraints are disrupting flights across China, India, Indonesia, and Thailand during a recent multi-day period in July, with 6,961 flights affected at major hubs. A recent mainland China snapshot alone showed 6,734 delays and 227 cancellations, with the heaviest congestion centered on Guangzhou Baiyun International Airport, Shanghai Pudong International Airport, and Beijing Capital International Airport. For passengers, that has meant long rebooking lines, crowded terminals, and knock-on delays spreading to Mumbai, Bengaluru, Jakarta, and Bangkok. Because severe weather is the main cause, compensation is usually unlikely under EC 261, but airlines should still provide care and assistance, including rebooking, refreshments, and accommodation if you’re stranded overnight.

Disruption details

Severe summer thunderstorms have disrupted 6,961 flights across some of Asia’s busiest airports during a recent multi-day period in July, with the worst congestion centered on Guangzhou Baiyun International Airport, Shanghai Pudong International Airport, and Beijing Capital International Airport in China.

For passengers, this has meant long queues at rebooking desks, crowded terminals, and overloaded call centers as delays spread from China into India, Indonesia, and Thailand. If you’re connecting through these hubs, even a short delay early in the day can turn into a much longer wait once aircraft and crews start arriving late.

One recent mainland China snapshot alone showed 6,734 delays and 227 cancellations. Guangzhou logged more than 800 delayed departures on one day, while rolling storm cells, heavy rain, and intermittent route closures forced airlines to stretch turnaround times, retime departures, and in some cases cancel lightly booked services.

The disruption hasn’t stayed inside China. Chhatrapati Shivaji Maharaj International Airport in Mumbai and Kempegowda International Airport in Bengaluru have each seen several hundred delays and dozens of cancellations as monsoon storms mixed with crew-availability issues. Farther south, Soekarno-Hatta International Airport in Jakarta and Suvarnabhumi Airport in Bangkok have been dealing with repeated arrival congestion as late aircraft from China and India ripple through later rotations.

What’s making recovery harder is that the weather is only part of the problem. Long-standing air-traffic and infrastructure constraints are leaving airlines with fewer ways to reroute around storm cells. Large areas of East Asian airspace remain under military control, which narrows the available flight paths when bad weather closes the usual ones.

On the ground, peak-season demand has stretched handling teams and terminal operations. Once lightning alerts, flooded ramps, or transfer-checkpoint bottlenecks slow things down, airports can struggle to get back on schedule. That’s why delays at the biggest hubs are now spilling into domestic and regional networks, rather than staying contained to one airport or one wave of departures.

Airlines have been trying to limit the knock-on effect by building longer schedule buffers, swapping in larger aircraft on selected services, and consolidating lightly booked flights to free up spare capacity later in the day. Those steps can help recover the schedule, but they can also mean retimed departures, aircraft changes, and last-minute rebooking for some travelers.

For now, the disruption remains active, and elevated delay volumes are expected to continue until more stable weather returns. With carriers still balancing post-pandemic fleet and staffing rebuilds against strong demand, this latest wave of delays is also adding pressure for better forecasting tools, more resilient schedules, and longer-term changes to regional airspace design.

If your flight has been affected, compensation is usually unlikely under EC 261 and similar passenger rights rules when severe weather is the main cause because that’s outside the airline’s control. Although compensation is unlikely here, that doesn’t mean you’re without support. Your airline should still offer care and assistance during long delays or cancellations, including rebooking or a refund, food and refreshments, and accommodation if you’re stranded overnight.
