A similar luggage misplacement happened to me recently, and advice I found in air france reviews emphasized providing full flight details, baggage tag number, and timestamp of last sighting—all in one single message. I applied that approach: sent a message listing flight number, baggage tag, arrival time, and included a photo of the baggage receipt. Less than two days later, I received a confirmation email saying my luggage was located at another airport and a courier would deliver it overnight. Ensuring all critical information appeared together seems to have triggered a fast and effective reply from their support team.
