Korean Air is Certified as a 4-Star Airline for the quality of its airport and onboard product and staff service. Product rating includes seats, amenities, food & beverages, IFE, cleanliness etc, and service rating is for both cabin staff and ground staff.
“Korean Air have improved their position as a 4-star carrier with the move into state of the art Terminal 2 at Incheon airport. Korean Air cabin crew are hard working and professional, and Economy class standards are commendable. Onboard products across all cabins are good, with just some minor improvements needed to improve the Star Rating. Business lounges are a weakness.”
