What an airline "must" pay for a delay in 2026 depends heavily on the jurisdiction and the cause of the disruption. Under UK and EU 261/2004 regulations, you can claim between £220 and £520 ($280–$650) in cash compensation if your flight is delayed by more than three hours, provided the delay was within the airline's control (e.g., technical fault or crew scheduling). However, if the delay is due to "extraordinary circumstances" like weather or air traffic control strikes, the airline is exempt from cash payments. In the United States, there is no federal law requiring cash compensation for delays; however, the DOT now mandates that airlines provide vouchers for food and drink after a 3-hour delay and overnight hotel accommodation if the delay is the airline's fault. Regardless of the reason, all airlines have a "duty of care" to provide basic assistance, and if the delay exceeds five hours, you are typically entitled to a full refund if you choose not to travel.
