As the Senate prepares to debate the Lieberman-Warner cap-and-trade bill, the airline industry's trade group says a mandatory cap on emissions is not necessary because the airlines have already taken steps to improve their environmental record. During today's OnPoint, James May, president and CEO of the Air Transport Association, discusses his industry's emissions record and explains how airlines are being affected by rising fuel costs. May explains what, he believes, Congress should be doing to help the airlines meet their alternative fuels and environmental goals. He also addresses the hot-button issue of airline consolidation and discusses how this could affect the airlines' bottom line.
