INTRO: Sun Country Airlines is asking the Department of Transportation to get involved in the competition between it and Northwest Airlines. Sun Country helped pay for a recent study that says Northwest has behaved in predatory ways on the the routes that Sun Country flies. Northwest says they're just meeting the competition on those routes, and that the government shouldn't interfere with the marketplace. The Department of Transportation and the Department of Justice have the authority to regulate airline competition. Joining us on the line to talk about what those departments can do in response to the study's findings is Congressman Jim Oberstar, who is the senior Democrat on the House Transportation committee. Eighth District DFL Representative Jim Oberstar.
