In 2026, your entitlement to compensation for delayed baggage is governed by clear international and domestic frameworks, primarily the Montreal Convention for international flights and Department of Transportation (DOT) rules in the U.S. If your bag is delayed, you are typically entitled to reimbursement for "reasonable" interim expenses, such as essential toiletries and a change of clothes, provided you keep all receipts. For U.S. domestic flights, the maximum liability limit is approximately $4,700 per passenger, while international limits hover around $1,700 to $2,000 (SDR 1,288). Most airlines officially declare a bag "lost" after 5 to 14 days, at which point you can claim the full value of the contents up to the legal limit. Crucially, you must file a Property Irregularity Report (PIR) at the airport before leaving the terminal to preserve your right to a claim. Be aware that luxury items or electronics are often excluded from standard airline liability, so separate travel insurance is still highly recommended for high-value luggage in 2026.
