Over 1,300 Flights Canceled & Diverted: London Heathrow’s Top 15 Most Affected Airlines

London Heathrow is Europe’s busiest airport by passengers. Due to a fire at a nearby electrical substation, it has no power, and its backups are insufficient for the required energy. As such, every inbound and outbound flight on March 21—exceeding 1,300—has been canceled or diverted. Perhaps 250,000-260,000 passengers will be affected on this day alone.
