Understanding Passenger Rights in Lost Luggage Disputes (2026 Update)

Navigating lost baggage claims starts with knowing your rights. In 2025, the U.S. Department of Transportation (DOT) reported a baggage mishandling rate of 0.54% for domestic flights, down from prior years, yet claims denials remain high at around 35% due to preventable errors. Globally, EU261 protections cover delays and losses, but pitfalls abound.

Successful claims hinge on compliance: DOT mandates airlines compensate up to $3,800 per bag, while EU261 caps at €1,300. Stats show 65% of well-documented claims succeed under DOT, versus 55% in EU261 due to stricter proof requirements.
