On Sunday, October 25, 2026, London Stansted Airport experienced a power surge that delayed approximately 250 flights and led to six cancellations, affecting critical airport operations.
The outage temporarily disabled security screening and baggage handling systems, causing long queues and terminal congestion as passengers underwent delayed processing. Staff worked throughout the day to manage the delays and assist travellers amid the disruption.
Prior to the airport power failure, rail services to and from Stansted were disrupted on Friday and Saturday due to fallen trees damaging overhead electrical cables near Stansted Mountfitchet. These rail issues compounded travel difficulties during a weekend
marked by severe weather from Storm Boelo, which brought heavy rain and strong winds across parts of the UK.
Stansted Airport confirmed that all disrupted operational systems were restored by Sunday evening. The airport issued an apology to passengers and stated its teams remained active supporting travellers and airlines during recovery. Officials did not provide a detailed cause for the original power surge or confirm links to the earlier railway infrastructure damage.
Passengers affected by cancellations are entitled to reimbursement or alternative transport under UK passenger rights. Travellers were advised on Monday, October 26, 2026, to verify flight status updates
individually. The combined impact of earlier rail disruptions and the airport power outage created significant complications for those travelling through the Essex airport.
