Hainan Airlines is a major Chinese carrier headquartered in Haikou, Hainan Province. Founded in 1993, it grew rapidly to become the fourth-largest airline in China by passenger volume, operating an extensive domestic and international network. The airline is a subsidiary of HNA Group, a large Chinese conglomerate, though HNA Group underwent significant financial restructuring in the early 2020s. Hainan Airlines has received multiple Skytrax five-star ratings, making it one of the few Chinese carriers to achieve this distinction. Hainan Airlines operates a modern fleet serving destinations across Asia, Europe, North America, and beyond. Despite the financial difficulties experienced by its parent company, it has continued to maintain a reputation for quality service and in-flight experience.
