The COVID-19 pandemic made 2020 one of the worst years in history for the global airline industry, with widespread layoffs, bailouts, and record revenue losses that are projected to continue into 2021. But the grim outlook for aviation isn’t stopping one Hong Kong airline startup from making plans to launch by this summer.

Budget airline Greater Bay Airlines (GBA) applied for the rights to fly 104 routes across Asia, according to a Hong Kong government gazette published Friday.

Nearly half of GBA’s potential routes fly to mainland China, where domestic air travel rebounded quicker than regional peers and surpassed 2019 air passenger figures by September due to low COVID-19 cases. GBA’s mainland China destinations range from first-tier cities like Beijing and Shanghai to smaller, third-tier cities like Weifang and Yancheng.

The startup also applied to operate flights to multiple cities in Japan, Vietnam, South Korea, and other popular regional tourist destinations.

The routes GBA applied for were left vacant after regional airline Cathay Dragon shuttered in October as part of a broader, pandemic-induced restructuring by Hong Kong’s flagship carrier Cathay Pacific. Former Cathay Dragon chief executive Algernon Yau Ying-wah joined GBA as CEO this month.

GBA will start with 300 staff members and three planes. It hopes to start flying by mid-2021, and aims to expand to 2,500 to 3,000 staff and 30 planes by 2025.

The airline is named for the Greater Bay Area, a Chinese-government promoted region encompassing Hong Kong, Macau, and nine mainland Chinese cities that Beijing hopes will become more economically-integrated to form China’s answer to the U.S.’s Bay Area and Silicon Valley.

Greater Bay Airlines was founded by Hong Kong property tycoon Bill Wong, who invested $258 million into the startup, banking on a recovery in Asia-Pacific air travel in 2021.

At the moment, COVID-19 travel restrictions on international tourists remain in place for most of Asia and plans for quarantine-free “travel bubbles” have failed to materialize.

GBA founder Wong is based in Shenzhen, the mainland Chinese city that sits across the border from Hong Kong, and has investments in China that include Shenzhen-based domestic carrier Donghai Airlines. Wong told the South China Morning Post in November that Donghai had recovered 98% of its pre-pandemic business, without specifying what measure of recovery he was using. (Donghai has a fleet of more than 20 passenger planes.)

Wong acknowledged the current situation of closed international borders and restricted air travel, but didn’t say how he thought it would affect GBA’s launch, except to cite China’s air travel rebound as proof that regional air travel can recover and that GBA, in his mind, will succeed.
