How were air passengers affected after the earthquake?

Specifically, at 14:09, the Flight Coordination Information Center reported receiving information from the Ho Chi Minh Area Control Center (ACC HCM) regarding the impact of the earthquake in Thailand on civil aviation activities. Accordingly, all flights to the two airports Suvarnabhumi (VTBS) and Don Mueang (VTBD) are temporarily suspended until further notice from the Thai authorities. These are the two airports where airlines from Vietnam are operating regular flights.

Immediately after receiving the report from the Flight Coordination Information Center, the Civil Aviation Authority of Vietnam directed the Air Traffic Management Center to deploy information to Vietnamese airlines, the National Flight Operations Center under the Air Defense - Air Force and collect information to evaluate and deploy air traffic flow management measures (ATFM), especially CTOT, as well as report the number of affected flights to the Civil Aviation Authority of Vietnam.

In addition, the Vietnam Air Traffic Flow Control Center received information from the Bangkok Air Traffic Flow Management Center and deployed ATFM measures to ensure effective coordination of flight operations in the area.

For flights arriving at VTBS airport, apply CTOT (Calculated Take-Off Time) measure for aircraft departing to this airport and require airlines and ATFM units to strictly comply with the issued CTOT.

For flights arriving at VTBD airport, a minimum departure interval (MDI) of 5 minutes/flight applies to flights departing from the same airport.

In the absence of CTOT, continue to apply 5-minute MDI/flight to control air traffic flow.
