Korean Air ranks No. 1 in the National Customer Satisfaction Index’s large full-service carrier category for the fourth consecutive year

[Financial News] Korean Air ranked first in the full-service carrier (FSC) category of the National Customer Satisfaction Index (NCSI) survey for the fourth consecutive year.
Korean Air announced on the 11th that it was selected as the top airline in the large-airline category of the 2026 National Customer Satisfaction Index survey, administered by the Korea Productivity Center. The awards ceremony was held that day at The Grand Lotte Seoul in Jung District, Seoul.
The NCSI is an indicator that evaluates companies’ service levels by surveying the satisfaction of customers who have directly used their products or services. Korean Air has ranked first in the large-airline category for four consecutive years, from 2023 through this year. This year’s survey covered 1,250 passengers who had used major domestic and international full-service carriers. Participants were customers aged 20 to 59 who had used the airline at least twice in the past six months.
Korean Air scored 81 points for customer satisfaction, 82 for perceived quality, 81 for customer expectations and 80 for perceived value in this evaluation. In particular, its perceived-quality score, which measures the level of service customers actually experience, rose from the previous year.
Korean Air has been working to improve services across all customer touchpoints, including inflight service, airport facilities and digital services. It is diversifying its in-flight meal options and updating its tableware, bedding and amenity items, while introducing Starlink-based inflight Wi-Fi to make travel more convenient for passengers. In particular, ahead of the launch of the integrated Korean Air on December 17, the company is also focusing on maintaining service quality. It plans to ensure stable operations and maintain service levels after integration through system integration, employee training and the integration of organizational cultures.
A Korean Air official said, “We are very pleased and honored to have achieved the distinction of ranking No. 1 in the NCSI for four consecutive years,” adding, “We will continue to do our utmost to establish ourselves as the world’s most loved airline through absolutely safe operations and differentiated service.”
