The Hong Kong government announced on June 28 that it would implement a regional flight “circuit breaker” for United Kingdom passenger flights arriving in Hong Kong starting July 1, due to a rise in variant cases of the CCP (Chinese Communist Party) virus.
The restriction affects all civil aircraft from the UK and lists the UK in its A1 very-high-risk category. Passengers who have stayed in the UK for more than two hours are restricted from boarding incoming passenger aircraft to Hong Kong.
