According to airport representatives, 11 incoming flights were forced to divert to alternative airports due to adverse weather.
Many flights have been forced to hold in the air or divert to nearby airports such as Cat Bi (Hai Phong), Tho Xuan (Thanh Hoa), Dong Hoi (Quang Binh), Phu Bai (Hue), and Danang, according to Vietnam Airlines.
Vietjet Air also issued a notice about adjustments to its flight schedules due to heavy rain at Noi Bai International Airport, advising passengers to check flight status and weather conditions before heading to the airport.
Bamboo Airways confirmed that two flights - QH102 from Danang to Hanoi and QH204 from Ho Chi Minh City to Hanoi - were diverted to Cat Bi Airport in Hai Phong on the morning of September 30. The airline warned that additional flights may continue to be affected if weather conditions do not improve soon.
The National Centre for Hydro-Meteorological Forecasting reported that strong convective clouds continued to develop over multiple areas in Hanoi. Over the next four hours, the capital city is expected to experience showers, thunderstorms, lightning, and strong gusty winds.
According to experienced pilots, takeoff and landing are the most critical phases of any flight. During heavy rain, strong winds, or thunderstorms, pilots may be forced to enter holding patterns or divert to alternate airports to ensure passenger safety.
Poor visibility and water on the runway significantly increase the risk of skidding, while strong crosswinds beyond aircraft limits can make landings unsafe. Under international aviation regulations, crews are required to abort landings if weather conditions fall below minimum safety thresholds.
Although diversions and delays cause inconvenience, these actions are taken to ensure safety. Airlines are offering support such as flight rebooking, refunds, meal services, and real-time updates through various channels.
According to the Vietnam Air Traffic Management Corporation (VATM), during the three days affected by Typhoon Bualoi, 5 flights were diverted to alternate airports; 7 were forced to perform go-arounds due to low-visibility conditions; 30 had to enter holding patterns; 2 were held on the ground, and 1 had to cancel takeoff due to substandard weather. More than 320 flights also changed their routes.
