The authority said it found glitches in its computer system during regular testing and maintenance in the early hours of Thursday. 

The Airport Authority said part of the facilities was back up and running from 8 am

The glitches affected check-in procedures between aisles A and E, it added.

It said it immediately activated its emergency response system and arranged for the airlines affected to use other aisles.

Part of the facilities was back up and running from 8 am, it added.

Cathay Pacific Airways, the city's flagship carrier, was one of the most affected, the local media reported.

Hong Kong's airport was one of the busiest international hubs before the COVID-19 pandemic, with more than 71 million passengers in 2019. 

Following the lifting of pandemic curbs and resumption of normal travel, the number of tourists arriving in Hong Kong has exceeded 1 million for the first time since the outbreak of the pandemic three years ago.
