This survey looked into airline satisfactions and ranked the top airlines on this basis. Right away, the article informed the reader that the survey was looking at seven factors in order to rank the top airlines.
This survey was published by Forbes and was conducted by the market reserach company, J.D. Power and Associates. The article also says that this is an annually published survey which adds to the amount in which you can trust where the data is coming from.
However, I was surprised that a large market research company would be so simple reporting their research in published article in Forbes magazine. Nowhere does it say how many people were surveyed or what the survey questions were. As a reader, it is beneficial to see satistics or numbers in research and I found none of that. Just simply the order in which the airlines fell based on rankings.
