Pilots from US Airways Group Inc.’s union picketed airport terminals in Los Angeles, Phoenix and Las Vegas on Tuesday, urging US Airways management to forge a new combined contract.

The pilots will march Thursday in Phoenix and Saturday in Las Vegas, where they will gather outside of the terminals but will not disrupt service, the union said in a statement.

The Arizona-based airline has already worked out labor deals with other employee groups but has yet to forge one with pilots, who complain management has dragged its feet in negotiations.
