My family was flying from Atlanta to Birmingham, England, through Charles de Gaulle (Paris). Of our four bags, only one arrived on time. During the next six days in England we tried multiple times every day to contact someone about our lost luggage. No one cared. We had a tracking number, but the tracking system was continually outdated and inaccurate. One of our bags arrived two days late and another five days late. It turns out that the last bag was put on our flight home with us, probably having sat at CDG for the entire trip. We were told by numerous people along the way that CDG is a black hole for luggage and that Air France does not care. We can verify that based on our experience.
