United, Continental to help Southwest in Newark

DALLAS -- United and Continental airlines will help Southwest Airlines expand in the New York market.

The move is designed to help United and Continental win approval from antitrust regulators to combine and form the world's largest airline.

United and Continental said Friday they will lease takeoff and landing slots at Newark (N.J.) Liberty International Airport to Southwest beginning next March.

The airlines said the arrangement was intended to address U.S. Department of Justice concerns about the proposed United-Continental combination.
