MADRID, Dec 4 (Reuters) - Spain should see air traffic return to normal within 24 to 48 hours, Public Works Minister Jose Blanco said on Saturday, after a wildcat strike by air traffic controllers paralysed airports for a second day.
"The normality will take some time, between 24 and 48 hours if the controllers return to work as they must," Blanco said during an interview on national television.
Airport authority AENA said the controllers were returning to work, but they expect Spanish airspace to be closed until 1800 GMT.
Earlier Spain's Socialist government declared a state of emergency and said those controllers who did not return would be breaking the law. [ID:nLDE6B301W]
