People flying into Hong Kong from overseas will be able to transfer to domestic flights from Zhuhai without having to pass through mainland immigration checkpoints from Tuesday.

The same deal in reverse will be in place for those flying domestically to Zhuhai and then abroad from Hong Kong, with passengers skipping the SAR's border clearances as they are taken straight to their boarding gates.

Shuttle buses will whisk transferring passengers from one airport to the other via the Hong Kong-Zhuhai-Macau Bridge.

Xinhua News Agency said the new “Fly from Hong Kong via Zhuhai” policy will more effectively link Zhuhai's 90 mainland air routes with Hong Kong’s nearly 200 international destinations.

The agency added that the arrangement will create more business opportunities for Zhuhai, while deepening collaboration among airports in the Greater Bay Area.
