BUENOS AIRES, Argentina (AP) - The ash cloud from a Chilean volcano is hovering over Buenos Aires again, grounding flights between the Argentine capital and many nearby airports. But officials say flights from Argentina's main international airport southwest of the city have returned to normal.
Airlines flying in Argentina have suffered for most of the 53 days since Chile's Cordon Caulle volcano began erupting.
Aerolineas Argentina, Austral and LAN Argentina airlines all grounded planes flying in and out of Aeroparque Jorge Newbery in downtown Buenos Aires.
LAN said its flights from the Ezeiza international airport were taking off and landing again.
The airlines are being cautious because volcanic ash can paralyze jet engines and severely damage their electronics.
