11 Types of Lost Baggage Coverage You Can Claim (What To File & How Much)

7. Long-term lost baggage — when bags are declared lost

Airlines generally escalate missing baggage to a “lost” status after a set period, commonly around three weeks, though that exact window varies by carrier. Once a bag is declared lost, carriers move from searching to full compensation processes. To prepare, keep your PIR, file any required forms, and submit a final damage or loss claim with a detailed inventory and proof of value. If items were expensive, provide receipts or bank statements showing purchases. Travel insurance can step in here, too, sometimes offering higher limits or broader coverage than the airline. When filing for final compensation, expect carriers to ask for documentation establishing ownership, the bag’s contents, and total value. Because carriers may apply depreciation or deduct salvage value if you keep parts of the bag, ask about salvage rules before disposing of damaged property. If you feel the airline’s settlement is too low, escalate to the airline’s customer relations department or consult consumer resources for further options.
