In 2026, whether an airline provides a hotel depends on the cause of the delay and the jurisdiction. Under EU261 (Europe) and similar 2026 U.S. DOT mandates, airlines must provide a hotel and transport if a flight is delayed overnight due to factors within their control (e.g., mechanical issues or crew scheduling). However, if the delay is caused by "extraordinary circumstances" like a massive blizzard or a nationwide ATC outage, many airlines are legally exempt from paying for your room, though they may offer "distressed passenger rates." In India, DGCA rules mandate hotel accommodation for delays exceeding 24 hours or overnight. Always ask the ground staff for a "hotel voucher" immediately; if they refuse, keep all receipts for a reasonable mid-range hotel and transportation to file a claim for reimbursement later.
