Hong Kong Airport's Terminal 2 deploys AI baggage, biometrics

Hong Kong International Airport has reopened Terminal 2 with extensive automation designed to handle departures with minimal staff intervention, positioning the facility as a test case for AI-driven airport operations as Asian hubs compete for passenger traffic.

The terminal, which began processing departures in May, features 68 self-service bag-drop counters equipped with proprietary AI systems that use 10 cameras per unit to scan barcodes and assess whether luggage meets safety requirements for automated handling. Airport officials say passengers can complete the biometric-enabled bag-drop process in approximately 45 seconds, according to details first reported by The Straits Times and International Airport Review.

Biometric gates replace passport checks

Twenty electronic security gates use facial recognition to admit passengers who have pre-registered their biometric data, eliminating the need to present passports at those checkpoints. The terminal also includes 15 smart security lanes that allow travelers to keep laptops and liquids under 100 milliliters inside carry-on bags during screening.

Airport officials estimate the combination of automation and redesigned passenger flow can reduce the journey from terminal entrance to boarding gate to under 20 minutes. Passengers traveling with only carry-on luggage can reach the restricted area roughly two and a half minutes after exiting ground transportation, according to the South China Morning Post.

Capacity expansion amid regional competition

The Terminal 2 redevelopment is part of Hong Kong's HK$141.5 billion ($18.1 billion) three-runway system project intended to increase annual capacity and maintain competitiveness against other major Asian aviation hubs. The revamped terminal is designed to handle up to 30 million passengers annually. Combined with Terminal 1's 70 million passenger capacity, the airport expects to reach a total annual capacity of 100 million passengers.

The Airport Authority projects Terminal 2 will process approximately 8 million passenger trips during its first year of operation. The entire airport served 61 million passengers in 2025, according to CNN.

Why it matters

Hong Kong's investment in automation reflects broader pressure on major airports to reduce operating costs and processing times as passenger volumes recover. The terminal's reliance on AI-powered baggage systems and biometric gates offers a model for airports seeking to minimize staffing requirements while maintaining throughput. Success or failure of the automation strategy will likely influence infrastructure decisions at competing hubs across Asia, where airports in Singapore, Seoul, and other cities are also deploying similar technologies to capture transit traffic.

Hong Kong International Airport was named Best Airport in the World at the Global Travel Awards 2026 and ranked as the eighth-busiest international airport by airline capacity in 2025, with 38.7 million seats, according to aviation data provider OAG.

Passengers currently checking in at Terminal 2 still travel by automated people mover to Terminal 1 to board flights. That arrangement is expected to change with the planned opening of the new Terminal 2 Concourse next year, which will provide boarding gates connected directly to Terminal 2.
