"HK Express confirms that the service system of our service provider Navitaire, which was previously impacted by the global Microsoft system outage, is gradually resumed," the airline said on its website.

"We are doing our best to ensure that all systems resume normal operation as soon as possible."

The four flights that were reinstated, flights 172, 173, 552 and 553, will be moved to different take-off slots.

The airline is urging passengers whose flights have been cancelled not to go to the airport, but to make sure their contact information on the "Manage My Booking" app is up to date and to check their email regularly for the latest flight arrangements.

"We appreciate our customers' patience and understanding," the airline said. "For other unaffected flights, passengers are advised to arrive at the airport as usual."

The Airport Authority said on Saturday that its operations had returned to normal. Contingency measures, including manual check-ins for some flights, had been in place on Friday.
