If a strike cancels your flight in 2026, your rights depend largely on who is striking. Under EU/UK 261 regulations, if the strike involves the airline's own staff (pilots, cabin crew), the airline is legally obligated to provide either a full refund or a reroute to your destination at the earliest opportunity. You may also be eligible for cash compensation if the strike was within the airline's control. However, if the strike involves "third parties" like Air Traffic Control or airport security, it is considered an "extraordinary circumstance," and no cash compensation is required—though the airline must still provide "Duty of Care" (hotel, food vouchers, and communication). In the United States, airlines are not legally required to provide cash compensation for strikes, but most 2026 Department of Transportation (DOT) rules mandate that they provide a full refund if you choose not to travel. Your first step should always be to use the airline's mobile app to rebook immediately, as phone lines will be overwhelmed during major industrial actions.
