US Airways (NYSE:LCC) is up after announcing that the U.S. government had given its merger with AMR Corp (NYSE:AAR) the green light. The combined company will become a massive player in the airline industry, and Motley Fool analyst Matt Koppenheffer thinks that this is a good move for the company in the long run. He also thinks that it's good news for the average flyer, as ticket prices may come down after the merger; however, it probably won't benefit people in smaller markets who have fewer options. Despite all the positives, Matt's still hesitant to invest in the airline industry, and suggests that investors wait and see what this merger means for US Airways before diving in.
