Your entitlement to a hotel depends heavily on the reason for the cancellation and the jurisdiction of the flight. Under EU Regulation 261/2004 (and similar UK laws), if your flight is cancelled and you are rebooked for the following day, the airline is legally required to provide "duty of care." This includes a free hotel room, transportation to the hotel, and meals, regardless of whether the cancellation was due to a technical fault or "extraordinary circumstances" like weather. In the United States, there is no federal law mandating hotels for cancellations; however, in 2026, most major U.S. carriers have made formal commitments to the Department of Transportation (DOT) to provide hotels and meals if the cancellation was within the airline's control (e.g., mechanical issues or crew scheduling). If the cancellation is due to weather or air traffic control, U.S. airlines are not required to pay for your hotel, though they may offer "distressed passenger" vouchers at a discounted rate. Always check the Department of Transportation’s Airline Customer Service Dashboard for the most up-to-date commitments from individual carriers, and keep all receipts if the airline fails to provide a voucher on-site.
