If your checked bag goes missing, the first step is to remain calm and head straight to the airline’s baggage service office at the airport. Provide them with your baggage claim ticket and a detailed description of your luggage. It’s essential to fill out a Property Irregularity Report (PIR) as soon as possible. This report will be crucial for tracking your bag and possibly filing a claim later on.Next, keep all related documentation, including boarding passes and any receipts for expenses incurred due to the delay or loss of your luggage. Most airlines have policies that reimburse passengers for essentials like clothing and toiletries while they search for your bag. Stay in regular contact with the airline for updates on your luggage status and make sure you understand their compensation policy in case the bag isn’t found within a reasonable timeframe. Patience and persistence are key during this process, but most lost bags are recovered within a few days.
