MIAMI (AP) - A former executive at a Peruvian airline has become the latest to plead guilty in a broad U.S. investigation into price fixing in the air cargo industry.
    
Ex-Cielos Airlines executive George Gonzalez on Wednesday pleaded guilty to price fixing conspiracy. He faces up to $1 million in fines and 10 years in prison but prosecutors say Gonzalez has agreed to cooperate in the probe.
    
Gonzalez and others were charged with conspiring to eliminate air cargo competition by fixing fuel surcharges for emergency shipments from the U.S. to Latin America following Hurricanes Katrina and Rita in 2005.
    
The Justice Department air transportation investigation has so far resulted in charges against 22 airlines and 21 executives. Four executives have gone to prison and more than $1.8 billion in fines have been imposed.
