The threshold for receiving a full refund or significant compensation for a flight delay depends heavily on the jurisdiction and the reason for the disruption. In the United States, as of 2026, Department of Transportation (DOT) rules mandate that passengers are entitled to a full refund if their domestic flight is delayed by more than 3 hours or an international flight by more than 6 hours, provided they choose not to travel on the rescheduled flight. In the European Union and UK (under EC 261/2004), you are generally entitled to fixed financial compensation (ranging from €250 to €600) if you arrive at your final destination more than 3 hours late, unless the delay was caused by "extraordinary circumstances" like weather. In India, the DGCA implemented updated 2026 norms allowing for a "48-hour look-in" free cancellation period after booking, and specific compensation tiers for delays exceeding 2 to 4 hours. It is vital to note that "getting your money back" (a refund) is usually only an option if you abandon the trip; if you still fly, you are instead seeking "compensation" for the inconvenience caused.
