Generally, no. Under EU Regulation 261/2004 and the equivalent UK261, an air traffic control (ATC) strike is considered an "extraordinary circumstance" that is outside of the airline's direct control. Because the airline cannot influence the labor decisions of a third-party government agency like an ATC provider, they are typically not required to pay the standard cash compensation (which ranges from €250 to €600). However, you are still entitled to your "Right to Care." If your flight is cancelled or delayed significantly due to an ATC strike, the airline must provide you with a choice between a full refund or a rerouted flight. Additionally, while you wait, they must provide food, drink, and hotel accommodation (if an overnight stay is required) along with transport between the airport and the hotel. In 2026, it is only possible to claim financial compensation if the strike involves the airline's own employees (such as pilots or cabin crew), as managing its own staff is considered an inherent part of the airline's business operations.
