Air Cambodia Co., Ltd. (IATA code: K6, ICAO code: KHV, abbreviated as ACC) is the national flag carrier of Cambodia, established by the Royal Government of Cambodia through a Sub Decree. In addition to operating commercial flights, ACC is responsible for VIP flights for the Royal Family and the Prime Minister, serving as the representative of Cambodia's civil aviation industry.

The history of the flag carrier of Cambodia dates back to October 15, 1956. For nearly 70 years, it has been dedicated to supporting Cambodia's vision of becoming a high-income nation. The government has consistently appointed 3-4 ministers or deputy ministers to serve on ACC's Board of Directors (BOD).

ACC operates extensive domestic and international routes, serving destinations across Southeast Asia, India, and Palau, as well as major Chinese cities including Guangzhou, Zhengzhou, Nanning, Hong Kong, Shenzhen, Fuzhou, Beijing, Shanghai, and Macau. Additionally, ACC holds exclusive seventh freedom rights for flights to Haikou, China. Through code-sharing agreements with Vietnam Airlines and other partners, ACC also connects passengers to destinations in France, the UK, and Australia. With a strategic fleet expansion plan, ACC aims to operate 33 aircraft by 2032, while continuing to open new popular routes in a structured manner.

In addition to the Royal Government of Cambodia, ACC's shareholders include Henan Airport Investment Group, a major state-owned enterprise in China, and Vietnam Airlines, the country's national flag carrier.

ACC is proudly serving the Kingdom and sincerely soaring together with the Kingdom. It is the only airline in Cambodia to obtain IATA Operational Safety Audit Certification (IOSA) and the only airline to receive a three-star rating from Skytrax. Guided by the principles of "attention to detail, localization, and internationalization," ACC fosters a corporate culture that treats employees as "internal passengers." Its service philosophy emphasizes "safety and warmth," while its standards aim to "benchmark global best practices." The airline's unique service identity is defined by the "Khmer smile" and its role as an "inheritor of Angkor civilization." By adhering to the motto "Progress every day, never stop improving," ACC has achieved revenue high growth in 2023 and 2024, fully recovering from the COVID-19 pandemic and entering a phase of rapid expansion.
