Heathrow Closure Triggers Global Travel Chaos
The shutdown of Heathrow Airport has caused widespread travel disruption worldwide, leaving tens of thousands of passengers stranded at airports overseas and forcing dozens of flights from the U.S., the Caribbean, and India to turn back mid-air.
As one of the world’s busiest airports, handling approximately 1,300 daily landings and take-offs, Heathrow’s closure following a fire at a nearby electrical substation has had a ripple effect on air travel across multiple continents. When the airport was shut down around 3 a.m., at least 120 flights were already en route to Heathrow. Hours later, dozens of these flights were still airborne, as pilots scrambled to find alternative landing sites.
Passengers from cities as far away as San Francisco and Perth in Australia were caught in the disruption, with data firm Cirium estimating that around 290,000 people scheduled to fly to or from Heathrow would be affected. Some flights were diverted to Amsterdam, Frankfurt, and Lyon, while others were forced to turn back to their departure points, including New York, Los Angeles, Mumbai, and Delhi. Air India has since canceled all flights to London.
All 34 scheduled flights from Dublin to Heathrow today were also canceled. A British traveler stranded in China with her husband expressed uncertainty about how they would return home, citing visa restrictions preventing them from checking into a hotel.
With major airports operating at full capacity, finding alternative landing sites has proven difficult. Flight tracking data shows a range of diversions, with flights from Bangkok redirected to Brussels, New York-bound flights rerouted to Iceland, and a Boston flight sent to Goose Bay Airport in Canada. Others have landed in Ireland, Munich, Frankfurt, Madrid, and alternative UK airports, including Cardiff and Manchester.
Among those affected were passengers of British Airways Flight BA56 from Johannesburg, many of whom had connecting flights to the U.S. and Italy. Dr. Don Cardy, 65, and his wife Sue, 60, were among those stranded, ultimately paying £400 for an Uber to Manchester to retrieve their parked car. Dr. Cardy described the situation as chaotic, citing a lack of communication and confusion in the baggage claim process.
Ruben Cortez, 44, from Portland, Oregon, had also arrived from South Africa after missionary work. He reported receiving minimal information, saying, "We just got an announcement saying we would not be landing in Heathrow, and we would be landing… I don't even know where we are."
Allie Renison, a UK trade expert traveling from Washington, found her flight rerouted back to the U.S. just over an hour before its scheduled landing in London. She described the experience as a "shock to the system," noting that passengers had little time to rebook before being returned to Washington. She expressed concern that she might remain stranded for days due to the backlog of affected flights.
Meanwhile, long-haul flights from Nairobi, Doha, and Tokyo have been diverted to alternative European airports such as Frankfurt and Helsinki. British Airways flights from Johannesburg, Lagos, and Cape Town have been redirected to Gatwick.
Passengers awaiting departures in various airports worldwide have expressed frustration over the lack of updates. One traveler in Toronto reported that Heathrow-bound flights were still listed as scheduled, despite the shutdown. Another traveler whose flight departed from JFK reported that their plane had been circling New York for hours before being forced to dump fuel and return to its departure point.
The fire that caused the disruption broke out at 8 p.m. on Thursday at an electrical substation near Heathrow. By the time the airport announced its closure six hours later, thousands of travelers had already been affected. A Heathrow spokesperson confirmed that the airport would remain closed until 11:59 p.m. on March 21, 2025, emphasizing that "passengers should not travel to the airport under any circumstances until operations resume."
Emergency crews from the London Fire Brigade have been working to control the blaze, which sent large plumes of smoke into the sky. Assistant Commissioner Pat Goulbourne stated that firefighters had led 29 people to safety and evacuated around 150 others as a precaution. A 200-meter safety cordon has been established, and local residents have been advised to keep their windows and doors closed due to the heavy smoke.
The cause of the fire remains unknown, but authorities continue to assess the situation. No injuries have been reported so far.
