Due to a major fire that resulted in a power outage, Heathrow Airport, one of Europe's busiest travel hubs, faced turmoil on March 21, 2025, causing at least 1,300 flights to be disrupted. An estimated 220,000 passengers were slated to travel through the airport that day, highlighting the scale of the impact as the closure reverberates globally.

Heathrow officials announced the airport would remain shut until 11:59 p.m. Friday, expressing empathy for impacted travelers and promising to expedite the resolution. "We understand this is disappointing for our passengers and are doing everything we can to manage the situation," said an airport spokesperson.

Travelers affected by the closure have been strongly advised against heading to the airport premises and are encouraged to maintain contact with their respective airlines for further instructions. On the day of the shut down, law enforcement diverted passengers attempting to access the airport, and vehicular traffic was redirected away from the area.

For the latest updates, most major airlines have published information on their websites about potential flight disruptions and the rescheduling process for canceled flights. Travelers are also encouraged to monitor airline social media platforms for real-time updates.
