French airport security personnel are on strike for a third straight day - leading to dozens of flights being canceled at a southeastern hub and delays at Paris' busiest airport, according to AP. Authorities at Lyon's Saint-Exupery airport said all flights were canceled until early afternoon Sunday, and Paris' airport authority said travelers faced major bottlenecks at security checkpoints at Charles de Gaulle. The delays in Paris mostly affected a key long-haul terminal - punishing international travelers in particular. Unions representing security personnel launched the walkout Friday to demand negotiations with management over an increase in pay. It has been timed for maximum effect during the holiday getaway season.
