This paper discovers why the qualification system of the cabin crew provided by the NCS has not been established in the cognition of airlines and as an alternative insists on reinforcing the effect of the NCS. To demonstrate this aspect, the second chapter says that the qualification system based on the NCS has a lot of expected effects such as improving the air service quality, and the third one introduces the CBT of foreign countries. The fourth one infers that the thoughts of the persons participating in the recruitment may have accounted for the phenomenon that the system is not enacted. Through this analysis, it is revealed that interviewers of the Korean airlines prefer assurance and empathy meaning personality and attitude and tangibility related to appearance but are indifferent to the remaining aspects of reliability, responsibility, and cooperation representing knowledge and skills in the whole evaluation criteria of cabin crew members’ competency. As seen in the examples of the foreign countries, I argue that this kind of idea should be reconsidered to supply credentials before hiring recruits, and the current NCS should be applied more rigorously
