Yes, Vietnam Airlines and its affiliate, Pacific Airlines, have announced multiple flight changes due to Typhoon Wipha, mainly between Ho Chi Minh City and Hai Phong. The Group also cautioned that multiple domestic and international flights on July 21 and 22 may experience delays and schedule disruptions due to the typhoon.

Typhoon Wipha has unleashed torrential rain across multiple regions as it barrels towards Vietnam, with rainfall exceeding 200mm, sparking concerns over flooding and landslides.

Typhoon Wipha has toppled trees and caused major flight disruptions in Hong Kong and at some nearby airports in China as it moved west off the country’s southern coast.

The death toll from a tourist boat accident in Vietnam’s Halong Bay climbed to at least 38 with several people still missing, the government said, as rescuers continued to search for survivors while bracing for the approach of Typhoon Wipha.
