4 star by Skytrax is a ranking done based on system of various factor. All the factors are listed on their website. OTHER factors are not considered. What we feel as not good enough, might be good for the people who participated in the survey, the PAX! We always think we know everything, and other people don't. As some people are complaining and condemning certain company, the company continues to grow. There will always be changes at new company as the it realigns it's direction. That is good corporate strategy. just look at the end result.
