Mediation ended between TWA and a union.

The National Mediation Board declared an impasse and released Trans World Airlines and its 6,000 flight attendants from mediation, triggering a 30-day cooling-off period that could lead to a March 7 strike. A board spokesman said binding arbitration was suggested, but the airline rejected it. TWA owner Carl C. Icahn has demanded and received wage concessions of 15% from the pilots and engineers unions and from all non-union employees, “yet he has raised his demands on flight attendants to 45% of their total wage, benefit and work-rule package, the equivalent of $110 million,” a union official said. “We will strike if Icahn is unwilling to accept our offer of 15% concessions.”
