A power surge on Sunday, October 25, 2026, at London Stansted Airport in Essex disrupted flights, delaying approximately 250 departures and cancelling six. The electrical surge affected airport operations and systems in the surrounding local area.
Flight Delays and Operational Disruptions
The power failure temporarily disabled key airport systems including security screening and baggage handling. Flight-tracking data obtained by Sky News from Flightradar24 confirmed about 250 delayed flights and six cancellations during the incident. This resulted in cascading effects on scheduled departures and aircraft rotations.
Passenger Impact and Terminal Congestion
Passengers faced lengthy queues and congestion inside the terminal as they awaited processing after security and baggage systems were knocked
offline. Some individuals reported waiting several hours during the outage. The airport teams provided ongoing assistance to travellers and airlines while operations were disrupted.
Restoration of Services and Support
Stansted Airport confirmed all affected systems were fully restored by Sunday evening, October 25, 2026. Airport personnel continued efforts to support passengers and airline staff as normal service resumed. The airport issued an apology to travellers for the disruption caused by the power surge.
Context of Severe Weather and Rail Disruption
The incident occurred during a weekend marked by Storm Boelo, which brought heavy rain and strong winds to parts of the United Kingdom. Earlier in the weekend, railway disruption near Stansted Mountfitchet
was caused by falling trees damaging overhead electrical cables, leading to cancellations of dozens of Stansted Express services. However, the airport did not establish a direct link between the earlier rail infrastructure damage and the Sunday power surge.
Official Guidance and Passenger Rights
Passengers travelling on Monday, October 26, 2026, are advised to verify individual flight statuses. Those affected by cancellations may have entitlement to reimbursement or alternative travel under UK passenger rights regulations. Passengers should retain receipts for reasonable expenses and contact their airlines for details on disrupted bookings. Updated departure and arrival information is available on the London Stansted Airport website.
