This aim of our scientific article is analysing how aviation industries can improve their customer’s satisfaction based on Kano Model. In fact, we noted in this article that there is no interaction found between « attractive » and « one dimensional » attributes. That’s why the Kano model shows us that it’s important to achieve the performance of « must be » attributes before achieving a best performance possible in « one-dimensional » attributes or « attractive » ones. We are going to introduce a solution to improve the Kano model regarding to the aviation industry.
