The carriers had high hopes of completing that merger by the end of this month, but a suit filed by the Department of Justice and several states including Arizona has put those on hold. Now hundreds of employees from the two airlines have traveled to Washington, DC for a rally and to talk up the merger to members of Congress. Our own Peter O'Dowd is in DC for the rally.
