Trinity Airlines said Wednesday, November 11, that it was named No. 1 in the 2026 National Customer Satisfaction Index (NCSI) survey organized by the Korea Productivity Center.

The NCSI is a customer satisfaction measurement model jointly developed by the Korea Productivity Center and the University of Michigan in the United States. It identifies the top performer in each category based on a comprehensive assessment of customer expectations, perceived quality, perceived value, and customer retention, among other factors, among customers who used the airline within the past six months. Trinity Airlines ranked first for the second consecutive year, earning consistently high scores across key evaluation categories.

Since beginning to introduce wide-body aircraft in 2022, Trinity Airlines has steadily expanded its medium- and long-haul network, including the Incheon-Sydney route. After adding major European routes, it also secured a North American network that includes Vancouver, establishing a global route network spanning Europe and the Americas. In April this year, it launched service on the Incheon-Jakarta route, accelerating the diversification of its medium- and long-haul routes.

It has also expanded its international route network centered on regional airports, improving travel convenience for local residents. Starting with the Busan-Hong Kong route in February this year, it has successively launched services on the Busan-Tokyo (Narita) and Busan-Kaohsiung routes, diversifying international flights departing from major regional airports.

The airline is also increasing investment in infrastructure to ensure safe operations. It is pursuing the construction of a new hangar at Incheon International Airport to improve operational and maintenance efficiency. In addition, in line with the introduction of the next-generation A330-900neo, it plans to expand its training, education, and maintenance systems based on its in-house aviation training center and strengthen its safety management capabilities.

Trinity Airlines continues to work to improve the customer experience and advance sustainable management. It has expanded the selection of vegetarian in-flight meals on long-haul routes and introduced pulp-molded meal containers that reduce environmental impact, enhancing both passenger convenience and environmental value. It has also revamped the user interface and user experience (UI/UX) of its official website and mobile platform to create a seamless booking experience from reservation through boarding.

Leveraging brand synergies within the Sono Trinity Group, the airline also offers integrated travel services through joint promotions linking air travel with hotels and resorts. Since completing its rebranding as Trinity Airlines last September, it has focused on ensuring the stable delivery of existing services and maintaining its operating systems. Going forward, it plans to continue improving its services to reduce customer inconvenience, maintain service quality, and enhance customer convenience and satisfaction.

A Trinity Airlines representative said, "Being named No. 1 in the National Customer Satisfaction Index reflects our efforts across all aspects of air services, including diversifying our routes, improving customer convenience, and expanding investment in safety. We will continue to make safe operations our top priority and grow into an airline that customers can trust."
