(IIAC) President Kim Kyoung Wook (left) and Airports Council International (ACI) Director General Luis Felipe de Oliveira on Sept. 14 each spread five fingers to indicate the Level 5 rating received by the Incheon airport, the highest under the ACI's Airport Customer Experience Accreditation. The airport received this historic grade at the ACI Customer Experience Global Summit at the Polish Aviation Museum in, Krakow, Poland. 

Incheon International Airport is the world's first and only airport to receive a "Level 5" accreditation.

Incheon International Airport Corp. (IIAC) on Sept. 14 at the ACI Customer Experience Global Summit held at the Polish Aviation Museum in Krakow, Poland, said the airport received the rating from the Airports Council International (ACI) program Airport Customer Experience Accreditation. 

In September last year, the Incheon airport was the world's first to receive a Level 4 rating. This year, the country's main air hub set yet another milestone with Level 5 in recognition of its efforts to understand customers, preemptively enhance their experience, and conduct systematic communication and cooperation.

ACI in 2019 adopted the accreditation program to evaluate management of the customer experience and service innovation activity at airports around the world. The comprehensive airport evaluation system uses a range of criteria and classifies airports from Levels 1-5.

Sixty airports participate in the program -- 18 in the Asia-Pacific region, 11 in Europe and 21 in the Americas. The top eight criteria for evaluation include understanding customers, strategies for improving their experience, service innovation and cooperation by relevant agencies.

Based on its airport operations receiving the Level 5 rating, IIAC plans to set service standards for the global airport industry in collaboration with AIC like developing global training courses on the customer experience.

IIAC President Kim Kyoung Wook said, "Based on the valuable result of obtaining the world's first Level 5 rating in customer service accreditation, which we received through the people's trust, active government support and the devoted efforts of the airport's 80,000 staff, we will lead new standards of the global airport industry as a trailblazer, not a fast chaser."
