Airport Authority Hong Kong announced the opening on 29 November 2019 of the extension to Terminal 1 (T1) at Hong Kong International Airport (HKG).
The extension includes a new aisle with 48 check-in counters, bringing the total number of check-in counters in T1 to 369. The number of smart check-in kiosks in T1 has also increased to over 100 at the extended departure level. In tandem with the opening of T1 extension, Terminal 2 (T2) will be decommissioned temporarily for expansion as part of the Three-runway System (3RS) project. Check-in counters at T2 suspended operation at around 23:00pm on November 28, and the check-in service for all airlines will now be conducted in T1. Ancillary services previously provided in T2, including the lost and found office and baggage storage service, have been relocated to T1. The decommissioned T2 is expected to reopen in 2024 after expansion, along with the commissioning of the entire 3RS. T2 will then be a full-service terminal providing both arrivals and departure services.
