Heathrow power outage: Know your rights as 1,000+ flights cancelled

A fire at Heathrow Airport triggered a power failure that forced Europe's busiest hub to shut its doors on Friday, leaving thousands of passengers stranded across the continent. The airport remained closed until midnight, during which time more than 1,000 flights were cancelled—a cascading disruption that rippled far beyond London. For Irish travellers, the impact was immediate and personal: at least 70 flights connecting Dublin, Belfast City, and Shannon to Heathrow were wiped from the schedule. Some passengers discovered their cancelled flights only upon arrival at their home airports, having travelled to catch connections that no longer existed.

The chaos exposed a gap between expectation and reality for many flyers. Airlines including Aer Lingus and British Airways began the work of rerouting passengers to alternative airports across the UK, but the process was chaotic and incomplete. Ryanair moved faster, announcing eight rescue flights between Dublin and London Stansted—four on Friday afternoon and four on Saturday morning—to absorb some of the stranded travellers.

For those caught in the disruption, the question became immediate: what are my rights? Under EU Regulation 261/2004, airlines must offer either a full refund or rerouting on the next available flight, or on a later flight of the passenger's choosing. If a passenger requests a refund, the airline has seven days to process it. That refund must cover the ticket price and, if there was a connecting flight involved, the cost of a return journey to the original departure point. The airline must also provide care and assistance—food, drinks, accommodation—while passengers wait for alternative arrangements, though this obligation does not extend to those who choose to wait for a flight later than the first available option.

Connecting flights add another layer of complexity. If a passenger missed a connection because of a delay on the first leg, EU regulations entitle them to a return flight to their original departure point. Package holiday customers face a different calculation: if they decide not to board an outbound flight, they risk forfeiting the entire holiday, making it essential to contact the tour operator or airline before abandoning the trip.

The power outage at Heathrow falls into a category that airlines often invoke to escape compensation obligations. Under EU travel regulations, carriers are not required to pay compensation if a flight is cancelled due to circumstances beyond their control—severe weather, strikes by airport or air traffic control staff, or other "extraordinary circumstances." A fire causing a power failure likely qualifies, but the definition of "extraordinary circumstances" is contested territory. Passengers have the right to challenge an airline's claim through aviation regulators such as the Irish Aviation Authority if they believe the carrier is stretching the definition too far.

Travel insurance offers a potential backstop, though coverage is inconsistent. Policies vary widely, and some may provide refunds if the airline does not. Under EU regulations, delays lasting eight to 12 hours can trigger compensation from an insurer, but complete cancellations often fall outside coverage. Passengers claiming through insurance will need written confirmation of the delay from the airport—a document worth obtaining immediately.

The practical first step is straightforward: check the website of your departure airport and search your flight number. That will confirm whether your flight is cancelled or merely delayed. From there, the path depends on the airline's response and the passenger's circumstances. For those affected by the Heathrow closure, the coming days will involve phone calls, emails, and careful reading of terms and conditions—the unglamorous work of extracting what the law promises when travel plans collapse.
