In brief
On March 21, 2025, London’s Heathrow Airport experienced a massive operational shutdown that severely affected air travel, disrupting at least 1,300 flights after a fire led to a fatal power outage. With Friday's passenger numbers estimated at around 220,000, the ramifications of the closure are expected to be felt globally as airlines work to address further cancellations and delays. Heathrow officials confirmed that the airport would remain closed until at least 11:59 p.m. on the same day, urging passengers not to approach the airport but instead to reach out to their airlines for the most up-to-date information and guidance. Local police were deployed to prevent access for travelers attempting to reach the airport.
