Chargeback surge looms for travel industry after Heathrow shutdown

A massive fire at the North Hyde electrical substation in Hayes, West London, late Wednesday night plunged Heathrow Airport into darkness and chaos, forcing a full closure of Europe's busiest aviation hub. While emergency responders quickly contained the blaze, the damage was already done: Heathrow's main power supply and backups were knocked offline, grounding operations and leaving hundreds of thousands of travelers stranded.

At least 1,351 flights were canceled by Fri. March 21, 2025, affecting nearly 291,000 passengers, according to Flightradar24. Officials estimate the cost to the global travel industry could reach tens of millions of dollars per day.

A chargebacks nightmare

But beyond the obvious logistical mayhem, payments professionals are bracing for a ripple effect few travelers consider: a spike in chargebacks.

Monica Eaton, CEO of Chargebacks911, warned that the fallout may prove costly for airlines and travel operators unprepared to deal with an influx of disputes.

"While anyone traveling today might be seeking an alternative flight from another airport or a refund," Eaton noted, "some—whether through convenience or frustration—might opt to file a chargeback, believing it will be easier than trying to arrange for a refund, especially for airlines whose refund policy does not extend to circumstances such as these."

A chargeback, Eaton stated, is a forcibly reversed transaction initiated by a cardholder and processed by the issuing bank, often resulting in additional fees and penalties for merchants. While designed to protect consumers from fraud or undelivered services, the process is increasingly seen by travelers as a shortcut to refunds—especially during crises.

"The stage is set for airlines to lose millions in reversed transactions, chargeback fees, and penalties," Eaton warned.

Proactive chargeback management

Eaton urged travel companies to get ahead of the curve. "Effective communication is key in circumstances such as these," she advised. "Offering clear and timely refunds could save from the irreversible fines and penalties associated with the chargeback process, which could cost airlines nearly four times as much as the transaction itself."

Eaton emphasized that in the wake of Heathrow's debacle, proactive chargeback management is no longer optional – it's essential.

"Clear, effective and responsive communication with customers goes a long way in ensuring travelers resolve issues with the merchant rather than their bank," she said. "That said, some customers will still opt to file a dispute, assuming it's the fastest option. For these cases, seeking third-party support is your best bet to defend against unnecessary disputes."
