American Air and US Air Merger

It's interesting to see American Airlines and US Airways merging. Oftentimes, we say that companies are best off merging when brand image is similar so the reputation of one does not lower the reputation of the other. Though some would argue, acquring a company with a better brand image could improve the brand image of the poor brand image company. In this case, American tends to have higher customer satisfaction ratings and US airways poorer. It seems as if US Airways is going to decrease the image of American Airlines, especially if they impose many of their regulations and use the same customer service agents. Where is this focus for both of these airlines now? Is it on the consumer? The price? Or somewhere else.
