Yes, you can claim compensation for delayed bags, but the amount and process depend on the flight's origin, destination, and the specific laws governing the carrier. Under the Montreal Convention, which covers most international flights, airlines are liable for "damages" caused by baggage delay, currently capped at approximately $1,700 per passenger. This compensation is intended to reimburse you for "reasonable" and "necessary" expenses incurred while waiting for your bag, such as toiletries and basic clothing. In the U.S., Department of Transportation regulations require airlines to compensate passengers for reasonable expenses up to $3,800 for domestic travel. To successfully claim, you must file a Property Irregularity Report (PIR) at the airport immediately, keep all receipts for your purchases, and submit a written claim to the airline—usually within 21 days of receiving the delayed bag. Note that the airline is not required to pay for luxury items or pre-existing belongings unless the bag is officially declared "lost" after 21 days.
