China's domestically developed C919 narrow-body jet completed its first scheduled international commercial flight on August 12, 2026, flying from Beijing Capital International Airport to Ulaanbaatar, Mongolia [1, 2, 3, 4]. The route is operated daily by Air China with flights CA723 and CA724 making round trips between the two cities [1, 2, 3, 4].

The C919 is built by the state-owned Commercial Aircraft Corporation of China (COMAC) and is designed to compete with Boeing's 737 and Airbus's A320 models [1, 2, 3, 4]. It can seat up to about 174 passengers [3]. The aircraft began domestic commercial service in May 2023 and has previously flown routes within China and between mainland China and Hong Kong [1, 4].

The first international flight was welcomed in Ulaanbaatar with a water salute ceremony [4]. Passenger Hu Yuan expressed hope for continual improvement, saying, "I hope our domestic planes continue to improve in terms of comfort and overall passenger experience – even outperforming Boeing and Airbus" [1].

COMAC has showcased the C919 at international airshows, including in Singapore in 2024 and 2026, and Dubai in 2025 [1, 3]. However, the C919 still relies on some foreign-made components, including parts from the United States, and it has not yet received certification from U.S. or European regulators [1, 3].

Despite the planned role of the C919 in reducing Chinese reliance on foreign manufacturers, COMAC delivered only 15 C919 aircraft in the past year, far below its target of 75 planes [3]. Aviation analyst Rob Morris criticized the slow progress, saying, "COMAC's pace of development and production is simply too slow to genuinely compete with Airbus and Boeing" [3]. Meanwhile, China confirmed a large order of 200 planes, engines and spare parts from Boeing in May 2026 [3].

The C919’s international debut marks a key milestone in China’s effort to expand its commercial aviation footprint beyond domestic routes. Upcoming service on the Beijing-Ulaanbaatar route will continue daily, furthering the aircraft’s operational experience on international routes [4].
