BUENOS AIRES, July 9 (Reuters) - The Argentine government plans to intervene in the administration of the country's biggest airline, Aerolineas Argentinas, which has been hit by a series of labor disputes, newspapers reported on Wednesday.

Daily La Nacion said Transport Secretary Ricardo Jaime had presented a draft of the intervention plan to President Cristina Fernandez. The report quoted an unnamed official source as saying the process was "in motion."

Another newspaper, Clarin, said the government eventually aimed to take control of the airline.

No one at the government or Aerolineas could immediately be reached to comment. Wednesday is a national holiday in Argentina.

A series of trade union disputes have affected the airline in recent months, causing flight delays and cancellations that have infuriated passengers.

Private Spanish travel group Marsans holds a 95 percent stake in Aerolineas, but it agreed in May to reduce its stake to 35 percent. Under that deal, the Argentine government would hold 20 percent, businessmen would take a combined 35 percent, company employees would hold 5 percent, and the South American country's provinces would own the remaining 5 percent.

Aerolineas Argentina was on the verge of bankruptcy in 2001 when Marsans bought it from a group controlled by the Spanish government. Together with Argentine airline Austral, Marsans handles more than 80 percent of domestic air traffic. (Reporting by Walter Bianchi; Writing by Helen Popper; editing by John Wallace)
