If your flight is cancelled due to a strike in Europe in 2026, your rights are protected under Regulation (EC) No 261/2004. The airline is legally obligated to offer you a choice between a full refund, re-routing to your final destination at the earliest opportunity, or re-routing at a later date of your choosing. Additionally, the airline must provide "Duty of Care," which includes free meals, drinks, and two phone calls or emails. if your new flight departs the next day, they must provide free hotel accommodation and transport to and from the airport. Regarding financial compensation (up to €600), the rules depend on who is striking. If it is an "internal" strike by the airline's own staff (pilots or cabin crew), you are generally entitled to compensation. However, if it is an "external" strike by air traffic controllers or airport ground staff, it is considered an "extraordinary circumstance" beyond the airline's control, and while they must still provide food and hotels, they are not required to pay additional monetary compensation.
