“Any activities that impact our ability to operate safely not only significantly disrupt the travelling public but also jeopardize the safety of our customers and our employees,” the airline said in a statement Saturday.

Hong Kong’s marquee carrier has come under pressure from mainland authorities after its employees earlier joined protests that originated from calls to resist a bill to allow extradition to the Chinese mainland.

The Airport Authority Hong Kong obtained a High Court order this week to extend an interim injunction granted on Aug 13 banning protesters from engaging in activities that unlawfully obstruct access to the local airport.

That injunction also covers Cathay City, “which is the operational hub for our global operations and as such includes facilities that are absolutely critical to our flight operations,” Cathay said in Saturday’s statement.

The Hong Kong Confederation of Trade Unions is planning activities for Aug 26, according to Cathay.
