Vietnam Airlines said that from February 2-3, airports experienced fog and low clouds, resulting in reduced visibility below operating standards. This led to many flights having to redirect their landings or being delayed and running behind schedule. This weather condition is expected to continue until February 8 (the 29th day of the Lunar New Year) during the nighttime and early morning hours.
To minimize negative impacts from the weather, Vietnam Airlines requires airlines to proactively monitor the weather situation, closely coordinate with airports, Air Traffic Management Centers, regional air traffic management companies, and aviation service providers at the airports to have appropriate operational plans and strategies.
In particular, passengers must be promptly notified and serviced in the event of changes to their transportation plans.
Vietnam Airlines requires that when encountering foggy conditions, Airports Corporation of Vietnam and affected airports must strengthen staff arrangements and management at the airport as well as timely release aircraft, coordinate with airlines to implement plans in case operational activities are affected by weather conditions.
Vietnam Air Traffic Management Corporation is responsible for instructing the Northern Region Air Meteorology Center, Air Traffic Management Centers, and non-towered facilities to proactively and promptly implement Collaborative Decision Making (CDM), monitor, and manage flight operations according to the weather situation. They must coordinate and support airlines and airports in their operational and safety work, ensuring the minimizing of negative impacts caused by weather conditions.
Airport Authorities must monitor, supervise, and manage the operational activities of airlines, units, and organizations providing services at the airports to ensure security, safety, handle issues arising during the aviation operations at the airports in accordance with regulations and their authority.
Prior to this, on the night of February 1 to the morning of February 2, a series of flights departing from Tan Son Nhat Airport to Hanoi, Thanh Hoa, and Nghe An were delayed, causing passengers to wait for a long time.
A representative from Vietnam Airlines shared that due to the influence of fog and bad weather at Noi Bai (Hanoi), Tho Xuan (Thanh Hoa), Vinh (Nghe An), and Phu Bai (Hue) airports, flight operators had to adjust their departure times by 2-6 hours for both incoming and outgoing flights from these airports during the early morning and morning of February 2.
