MILAN (AP) Alitalia's main pilots' union has announced a four-hour strike for Oct. 29 to pressure management for details on how they intend to return the struggling carrier to health.

UILT secretary-general Marco Veneziano said in a statement the union could hold more strikes up to a combined total of 48 hours until it receives "a credible plan" for saving Italy's flagship airline. The union rejects proposals for layoffs and demands a clear plan that includes an international partner and new management.

Alitalia's shareholders have agreed to inject 300 million euros ($410 million) into the airline as part of an overall 500 million-euro plan to save it from bankruptcy. Shareholders, including Air France-KLM with a 25 percent stake, have until mid-November to declare how much they are willing to inject.
