A proposal by American Airlines to widen its reach reignited antitrust concern on Monday over the prospect of ``mega-carriers'' with colossal power over the industry.

``This deal would trigger the airline consolidation we have feared in the wake of a proposed United-US Airways merger,'' said U.S. Rep. Louise Slaughter, a New York Democrat and a leading congressional opponent of the United deal. ``It would be a travesty for the new administration to let this go forward.''
