Air China's C919 Begins First Scheduled International Service to Ulaanbaatar

Air China marked a significant milestone on August 12, 2026, when its COMAC C919 jet completed its inaugural international commercial flight. Flight CA723 departed Beijing Capital International Airport mid-afternoon and touched down at Ulaanbaatar's Chinggis Khaan International Airport shortly before 5 p.m. local time, celebrated by a traditional water cannon salute to honor the occasion. This event marks the first time the Chinese-developed C919 has operated a scheduled international passenger service beyond Chinese territory.

The new daily route between Beijing and Ulaanbaatar is now regularly operated by Air China's fleet of C919 aircraft. The service, which uses flight numbers CA723 outbound and CA724 inbound, runs seven days a week, replacing prior operations on this route that used Boeing 737 jets. The switch to the domestically produced C919 highlights China's push to utilize homegrown aircraft for both domestic and nearby international markets.

Built by the Commercial Aircraft Corporation of China (COMAC), the C919 is the first narrowbody jet developed independently in China. It seats between 158 and 192 passengers, depending on configuration, and offers a range spanning 4,075 to 5,555 kilometers, positioning it as a competitor to established models like the Airbus A320 and Boeing 737. The jet meets recognized international airworthiness standards but awaits certification from some Western regulatory authorities, which currently limits its broader global sales opportunities.

Since the C919's first commercial flight operated by China Eastern Airlines in May 2023, the fleet has gradually expanded, with Air China receiving its first unit in August 2024. Today, Air China operates a dozen C919s. Alongside China Eastern Airlines and China Southern Airlines, the carriers have introduced the type on more than 57 routes, serving 26 cities and transporting over 7.5 million passengers. Until now, most services with the C919 remained within China, with only demonstration flights and limited routes to Hong Kong extending beyond.

The choice of Ulaanbaatar for the first scheduled international route is seen as both practical and symbolic. Located approximately 1,200 kilometers from Beijing, the short trip allows for manageable same-day round trips and swift ground support if necessary. It also represents a strategic advancement in establishing China's aviation footprint in neighboring regions, especially since another Chinese-built aircraft, the Xian MA60, already operates between Hohhot and Ulaanbaatar, further solidifying the presence of domestically manufactured planes at the Mongolian airport.

COMAC’s ambition with the C919 is to carve out market share from established Western aircraft manufacturers, reducing China's reliance on foreign technology. While regulatory challenges and production scale currently limit its worldwide reach, the successful launch of an international scheduled service demonstrates the aircraft’s readiness for regional operation and underscores incremental progress towards wider global acceptance.

Passenger reactions on the inaugural flight expressed national pride in traveling on a Chinese-built airliner abroad. For COMAC and Air China, this flight is a significant step—transitioning the C919 from a primarily domestic workhorse to an aircraft engaged in routine international service. This move not only symbolizes technological progress but also reflects strategic efforts to compete more directly on regional air routes.

While the C919's future growth will hinge on securing additional certifications, maintaining operational reliability, and meeting customer demand, the Beijing-Ulaanbaatar service serves as a concrete example of China's expanding aviation capabilities. It marks a cautious but decisive foray into international commercial aviation markets, moving beyond demonstration flights toward a sustained global presence.
