Flight attendants at Hawaiian Airlines have ratified a contract for single-aisle aircraft for flights to the U.S. West Coast. "Everyone at Hawaiian wants us to keep our position as the market leader in service quality, cost efficiency and choice of destinations and ordering the A321neo will secure this legacy on routes between the U.S. West Coast and Hawaii beyond the middle of this decade," said Mark Dunkerley, president and CEO of Hawaiian Airlines, in a statement.
