If your baggage is delayed on a Delta flight in 2026, you are entitled to reimbursement for "reasonable and essential" expenses incurred while you wait. Under U.S. DOT regulations for domestic flights and the Montreal Convention for international ones, the liability limit is approximately $3,800 for domestic and roughly $1,700–$1,950 for international. However, reimbursement is not a flat cash payment; you must submit receipts for items like toiletries, undergarments, and necessary clothing. Delta typically processes these claims quickly once a "Property Irregularity Report" (PIR) is filed at the airport. It is a "pro-tip" to keep all your original receipts and only purchase items that are truly necessary for your immediate needs; luxury fashion or non-essential electronics are rarely covered under these consumer protection rules.
