Air travel to resume in dark red provinces from Sept 1
The Civil Aviation Authority of Thailand plans to allow resumption of air travel from September 1 in the “dark red” areas of Covid-19.

The decision was made after the Centre for Covid-19 Situation Administration on Friday announced permission for inter-provincial travel in those areas.
However, airlines will have to prepare strict preventive measures against Covid-19, for their operations in the dark red areas.
