Air China flew a COMAC C919 from Beijing to Ulaanbaatar on 12 August 2026, the Chinese-made jet’s first scheduled international commercial flight since it entered service in 2023.
It is a short, symbolic hop rather than a global debut, but it is the clearest sign yet that China’s answer to the Boeing 737 and Airbus A320 is starting to move beyond its home market.
Air China’s C919 just flew its first international route
Air China operated the flight as CA723, replacing a Boeing 737 MAX 8 that had been flying the same route, according to Aviation A2Z.
- Route: Beijing Capital International Airport to Chinggis Khaan International Airport in Ulaanbaatar
- Flight numbers: CA723 outbound, CA724 on the return
- Frequency: Daily, in both directions
- First flight: 12 August 2026
The C919 was first delivered to China Eastern Airlines in December 2022 and entered commercial service in May 2023. Since then it has flown mostly domestic Chinese routes, alongside cross-boundary flights to Hong Kong that began in January 2025.
Beijing to Ulaanbaatar is different: it is the C919’s first scheduled flight to a foreign country, which is why Chinese and international aviation outlets are calling it the aircraft’s first true international service.
What is the C919?
It is China’s first homegrown narrowbody jet, built by the state-owned manufacturer COMAC to compete with the Boeing 737 and Airbus A320 on short and medium-haul routes.
Depending on the airline’s seating layout, it carries between 158 and 192 passengers with a range of 4,075 to 5,555 kilometres, putting it firmly in the same class as the jets you already fly on most short regional trips.
Three Chinese carriers now operate the type: Air China, China Eastern Airlines and China Southern Airlines.
Before the Mongolia flight, the three carriers had flown the C919 on 57 routes across 25 cities and carried more than 7.5 million passengers, as of 11 August 2026, according to China Daily. Adding the new Beijing-Ulaanbaatar service takes the total to 58 routes across 26 cities, per Global Times.
What keeps the C919 out of the US and Europe for now is the lengthy validation and paperwork process any new aircraft type must clear, not a known safety defect.
The jet still lacks full certification from the FAA and EASA. EASA pilots have been running certification test flights on the C919 in Shanghai since January 2026, but until that process concludes, the aircraft cannot be sold to airlines or fly scheduled routes in either region.
Will you end up flying on one?
Right now, a C919 flies domestic Chinese routes, the cross-boundary service to Hong Kong, and this single Beijing-Ulaanbaatar route. Travellers connecting through the Gulf, Europe or North America will not encounter one any time soon.
If your itinerary runs through China on Air China, China Eastern Airlines or China Southern Airlines, though, you could already be booked on one without realising it.

[Editor note: Could not conclusively confirm whether COMAC has an active, formal type-certification application pending with the US FAA specifically, as distinct from the EASA process. Several 2025-2026 reports suggest COMAC has prioritised EASA certification and may not yet have a live FAA filing. Recommend confirming directly with COMAC or the FAA before publication if this distinction is important. Checked 14 August 2026.]
