C919 to fly first international route on Aug. 12 with Air China

Air China will deploy the C919 on a daily Beijing-Ulaanbaatar service from Aug. 12, marking the first regular international route for China's domestically produced narrowbody jet.

China's C919 narrowbody jet will enter regular international service for the first time on Aug. 12, as Air China deploys the domestically produced aircraft on a daily route from Beijing to Ulaanbaatar, according to the carrier.

"The C919 has essentially moved from trial operations into a new stage of scaled and routine commercial operations," said Zhu Keli, founding director of the China Institute of New Economy.

The milestone comes as the C919 program accelerates. By the end of April, the three largest Chinese carriers operated 36 C919 aircraft — 15 with China Eastern Airlines, 11 with Air China and 10 with China Southern Airlines, according to Flight Master data. The fleet had completed more than 42,000 commercial passenger flights since entering service in May 2023, with April flight volume surging 117.9 percent year-on-year to 3,190 flights. Some aircraft logged as many as 10.7 flight hours a day, approaching utilization rates of mature narrowbody jets such as the Boeing 737 and Airbus A320 families.

The expansion into international service signals COMAC's confidence in the C919's reliability and opens a new chapter for China's ambitions to challenge the Boeing-Airbus duopoly in the single-aisle market. IBA Group forecasts deliveries could reach around 28 aircraft in 2026, up from 32 cumulative deliveries by the end of 2025, though international certification and supply chain constraints remain key hurdles.

The Beijing-Ulaanbaatar route, operated daily, connects China's capital with Mongolia's largest city — a relatively short international sector that allows COMAC to demonstrate the aircraft's cross-border capability without the range demands of longer-haul international routes. The C919 has a flying range of 4,075 kilometers to 5,555 kilometers and seats 158 to 192 passengers, comparable to the Airbus A320neo and Boeing 737 MAX families.

Since its first commercial flight in May 2023, the C919 has linked 29 airports — 28 on the Chinese mainland and one in Hong Kong. The aircraft marked the ninth anniversary of its maiden flight on May 5, 2026, nine years after its first test flight in 2017. More than 1,000 orders have been booked at home and abroad, according to COMAC.

Production ramp and supply chain

COMAC is accelerating production capacity as deliveries broaden beyond China Eastern. Air China, China Southern and China Eastern each purchased 100 C919 aircraft, with deliveries scheduled between 2024 and 2031. Suparna Airlines, a Shanghai-based private carrier, is set to become the first private operator of the C919, planning to introduce 30 aircraft and gradually compose its fleet exclusively of the model.

However, challenges remain. Supply-chain vulnerabilities, shortages of experienced maintenance personnel and continued reliance on imported components for some core systems constrain the production ramp, analysts said. International certification from Western regulators — a prerequisite for sales in Europe and North America — has not yet been secured.

The C919's international profile is rising. At the Singapore Airshow in February 2026, the aircraft conducted demonstration flights as COMAC sought to build recognition in Southeast Asia. Zhu said the C919 was likely to evolve from a supplementary aircraft into a main workhorse of China's domestic narrowbody fleet over the next three to five years, particularly on high-density routes of 1,000 to 3,000 kilometers. Beyond that, emerging markets in Southeast Asia, Africa and Latin America represent the most likely export destinations.
