Greater Bay Airlines

Is Greater Bay Airlines safe?

Yes, on the record so far. Greater Bay Airlines (GBA) received its Hong Kong operating certificate in October 2021 and flew its first scheduled flight, to Bangkok, on 23 July 2022. It has had no accident and lost no aircraft. Hong Kong's Air Accident Investigation Authority, which publishes its reports, has never opened an investigation involving it. We score it 83.

The catch is time. Four years with a small fleet of Boeing 737s is not enough to judge an airline the way we judge Cathay Pacific, which has decades of data. We give it the same accident score as other young airlines with clean records, not the top band.

A small Hong Kong airline

GBA is the youngest of Hong Kong's passenger airlines, a private company chaired by the businessman Wong Cho Bau. It is not part of the Cathay group that owns HK Express, and not part of the HNA group that owns Hong Kong Airlines.

It holds its own Hong Kong air operator's certificate and flies under its own HB code, so everything on this page counts here. Hong Kong's Air Transport Licensing Authority has licensed it for scheduled flights on 176 routes, though it uses only a fraction of them.

The airline has had growing pains. In January 2025 it cancelled 128 flights in February and March, affecting about 5,500 passengers. It blamed late deliveries of new aircraft and inspections of existing ones, and said an internal review had found "negligence in the flight scheduling process". That is a planning failure, not a safety event: no aircraft flew that should not have. But it shows how thin a margin a small fleet has when one jet is out of service.

What does it fly?

Only Boeing 737s. The airline said in January 2024 that it flew five 737-800s. In March 2023 it ordered 15 737-9s, and the first arrived from Seattle on 22 November 2025 and went into service at once. The airline publishes no running total of its fleet.

The 737-800 has a long, good record, but it is an older design without fly-by-wireFly-by-wireA flight control system in which the pilot's inputs go to computers, which then move the control surfaces. Many such systems also stop unsafe manoeuvres.More in the glossary controls, and GBA does not publish the age of its 737-800s. The 737-9s are new and modern. We score the fleet 72: better than an all-737NG fleet, below a young Airbus fleet such as HK Express's.

The MAX question comes up often because of the January 2024 Alaska Airlines door-plug blowout on a 737-9. GBA said at the time that its ordered aircraft use the emergency exit door in that position rather than a plug, and that deliveries had not started. The type went back into service worldwide after inspections, and the airline took its first 737-9 almost two years later.

Where does it fly?

All flights start or end at Hong Kong International Airport, a modern three-runway hub. The network covers Japan (Tokyo, Osaka, Fukuoka, Sapporo, Okinawa), Taipei, Bangkok, Manila, Surabaya from September 2026, and seasonal flights to places such as Phuket, Da Nang and the Maldives. On the mainland it skips the big hubs and flies to smaller cities: Zhoushan, Yichang, Guilin, Zhangjiajie, Enshi, Datong, Dunhuang and Hohhot.

Those mainland airports are where the network is harder than Cathay's or HK Express's. Zhangjiajie and Enshi sit among steep hills in western Hunan and Hubei, and Dunhuang and Hohhot bring desert dust and cold northern winters. At home the risk is the weather: typhoons from July to October, summer thunderstorms and windshear on approach to Hong Kong. We score the environment 80, a little below the 84 we give Hong Kong's other short-haul airlines.

Oversight

Hong Kong runs its own aviation regulator, the Civil Aviation Department, separate from mainland China's CAAC. It holds FAA Category 1FAA IASAThe US FAA's check of whether a country's aviation regulator meets ICAO standards. Category 1 means it does; Category 2 means it does not.More in the glossary, and no Hong Kong airline is on the EU Air Safety ListEU Air Safety ListThe European Commission's list of airlines banned or restricted from flying in EU airspace because they do not meet international safety standards.More in the glossary. The investigations go to a separate body, the AAIA, which publishes preliminary reports, interim statements and final reports, though it is slow. GBA appears on IATA's member list, which requires an IOSAIOSAThe IATA Operational Safety Audit, an international audit of an airline's safety management and operations. Every IATA member must pass it.More in the glossary safety audit. We give it the same 88 as Hong Kong Airlines and HK Express.

Before you fly

• Typhoon season (July to October): when Signal No. 8 is raised, Hong Kong flights stop or bunch up. A small airline has few spare aircraft, so rebooking can take days. Book flexible fares in these months.
• Mainland mountain cities: flights to Zhangjiajie and Enshi are more often delayed or diverted by low cloud and fog. Plan a day of slack if you have an onward connection.
• Power banks: Hong Kong's rules on lithium batteries in the cabin are strict. GBA posts its current rules on its website; check them before you pack.

How we scored it

Oversight (88) is the strongest factor: Hong Kong's regulator and investigator are among the better ones in Asia, and the airline holds IOSAIOSAThe IATA Operational Safety Audit, an international audit of an airline's safety management and operations. Every IATA member must pass it.More in the glossary. The accident record (88) is clean but only four years long. The fleet (72) is the weakest: 737-800s of undisclosed age, with new 737-9s only now arriving.
