Yes, in 2026, most major airlines are required by law or company policy to rebook you on the next available flight at no additional cost if they cancel your journey. Under updated 2026 regulations from bodies like the US DOT and India's DGCA, if a cancellation occurs due to an airline's operational issue, they must offer you the choice between a seat on another flight or a full, automatic cash refund—including all taxes and fees—within 7 to 14 days. If the new flight doesn't depart until the following day, many premium carriers are also obligated to provide hotel accommodations, ground transportation, and meal vouchers. However, if the cancellation is due to "force majeure" (uncontrollable events like extreme weather or global strikes), the airline is still required to rebook you, but they may not be legally forced to pay for your hotel stay. Always check your airline's specific "Contract of Carriage" via their mobile app as soon as a cancellation notice is received, as most modern systems now allow you to self-select a new flight immediately without waiting in line at a help desk.
