Heathrow Airport Closure Causes Major Flight Disruptions

Over 1,300 flights were disrupted at Heathrow on Friday due to a major fire that resulted in a power outage. Travelers are advised to stay away from the airport and check with their airlines for updated flight information as the situation evolves.

On March 21, 2025, London’s Heathrow Airport, one of the busiest in Europe, faced unprecedented disruptions with the cancellation of at least 1,300 flights as it remained closed following a major nearby fire that caused a power outage. Approximately 220,000 passengers were scheduled to transit through the airport on that day, and the closure is expected to affect air travel on a global scale as airlines manage the cascading consequences.

Heathrow's management announced that the airport would remain shut until at least 11:59 p.m. on Friday, urging travelers to stay away from the airport due to safety concerns. "We understand this is frustrating for passengers, but our priority is ensuring a safe resolution to the incident," remarked a spokesperson for Heathrow.

Travelers whose plans have been impacted by the closure are strongly advised not to head to the airport but to directly contact their airlines for the latest information regarding flight status. Emergency services have been redirecting passengers attempting to reach Heathrow, and road access has been severely affected.

Airlines have begun communicating with their customers, with many providing respective updates via their websites and social media platforms regarding the situation, including protocols for rescheduling flights that have been canceled. Travelers are encouraged to remain informed as disruptions are expected to continue in the coming days.
