If your luggage fails to appear on the carousel in 2026, the first and most critical step is to file a Property Irregularity Report (PIR) at the airline’s baggage service counter before leaving the airport. You will need your baggage claim sticker and a detailed description of your bag. Ensure you get a reference number and a direct phone number for the baggage office. Most "lost" bags are actually just delayed and are typically delivered to your hotel or home within 24 to 48 hours. In the meantime, most airlines will reimburse you for "reasonable incidental expenses" like toiletries and a change of clothes—save all your receipts! In 2026, many travelers use personal GPS trackers like AirTags, which allow you to tell the airline exactly where your bag is, often speeding up recovery. If your bag is missing for more than 21 days, it is officially declared lost, and you can file a formal claim for the value of the contents (up to $3,800 on domestic U.S. flights). Don't forget to also check your credit card benefits or travel insurance, as many offer secondary coverage that kicks in faster than the airline's compensation.
