Hong Kong riot police took up position at the main rail station serving the airport on Sunday to prevent a new anti-government protest targeting air travel after a night of violent street clashes in the Chinese-ruled territory.
Protesters have targeted the airport before, occupying the arrivals hall, blocking approach roads and setting street fires in the nearby town of Tung Chung, and trashing its subway station.
The Airport Express, which takes passengers under the harbor and across a series of bridges to the airport, built on reclaimed land around an outlying island, was only allowing passengers to board in downtown Hong Kong, not on the Kowloon peninsula, the Airport Authority said.
And only people holding flight tickets were allowed to enter the terminal. Bus services were also affected.
