Airlines canceled flights and passengers had to go home without their luggage. More than 10,000 suitcases and other bags sat at Roissy-Charles de Gaulle airport, The Local.fr reported Friday.
The bags were to be sent to their owners, said Olivier Janicaud, a spokesman for Air France, the airport's major carrier.
Car insurance claims precipitated by the unseasonable weather could exceed $130.6 million, officials said. More than 100,000 people had already filed claims related to snow and ice. .
A representative for an association of truck drivers estimated additional shipping costs could be $26.1 million a day because of vehicles disabled by road conditions and drivers being forced to make lengthy detours around accident scenes.
