Can a Power Bank Catch Fire on a Plane? What This Month's IndiGo Incident Actually Shows

Somewhere over south-central India on October 11, a passenger's power bank sitting in the overhead bin on an IndiGo flight started to smoke, then caught fire. It's exactly the kind of story that lands hard if you already feel uneasy about flying — a fire, mid-air, with nowhere to go. So it's worth slowing down and looking at what actually happened, because the full sequence tells a far less frightening story than the headline.

What happened on IndiGo Flight 6E-6115

The Airbus A321neo was cruising at 35,000 feet on a flight from Delhi to Chennai when, about 80 nautical miles north of Hyderabad, a power bank stored in an overhead locker began to burn. Cabin crew used the aircraft's onboard fire extinguishers to bring the fire under control and secure the device, according to Aviation Herald reporting carried by AeroInside. The crew diverted to Hyderabad as a precaution, and the aircraft landed safely about 19 minutes later with no further incident. No injuries were reported.

That's the entire event: crew noticed the problem, used equipment that exists specifically for this situation, and landed the plane without drama. It's also, almost exactly, what the system is designed to do.

Why power banks and phone batteries catch fire at all

The batteries in power banks, phones, laptops, and vapes are lithium-ion, and the failure mode behind nearly every one of these stories has a name: thermal runaway. If a cell is damaged — dropped, crushed, punctured, or charged with a cheap or faulty charger — a short circuit inside it can trigger a chain reaction that heats the battery faster than it can cool, according to an explainer from the National Business Aviation Association. The result is the kind of sudden smoke or flame passengers sometimes film: dramatic to witness, but a well-understood chemical process rather than a mystery.

That same understanding shapes how crews are trained. A standard fire extinguisher can knock down the visible flame, but it doesn't stop the chemical reaction happening inside the cell — only cooling the device, usually with water, actually halts thermal runaway. That's why cabin crew are trained to keep cooling an overheating device rather than extinguishing it once and walking away, and why a growing number of airlines now carry fire-resistant gloves, face shields, and purpose-built containment bags as backup equipment.

How often does this actually happen?

Rarely, relative to how many people fly. The FAA recorded 93 incidents in 2025 in which a battery smoked, ignited, or produced extreme heat on board a US aircraft — a modest increase on the year before — and the large majority, 80 of the 93, were on passenger flights rather than cargo aircraft, according to FAA data summarized by Lion Technology. Power banks and other battery packs were the single largest category behind those incidents, ahead of e-cigarettes and vapes, then phones.

Set that number against the roughly 44,000 flights the FAA says it handles every single day in US airspace alone, and the picture is one of a known, monitored, low-frequency risk, not a hidden danger waiting to catch travelers off guard. It happens often enough that every crew member is trained for it, and rarely enough that most people will fly for a lifetime without ever seeing it.

Airlines are tightening the rules anyway

Because these incidents have ticked up industry-wide, several major carriers have moved to reduce the odds further. American Airlines now limits passengers to two power banks or portable chargers, each rated at 100 watt-hours or less, and requires that any charger in use stay within sight and reach rather than tucked into an overhead bin — a policy that took effect in May 2026, aimed at giving crew the fastest possible access if a device does start to heat up, according to ABC7 News. Other carriers have introduced similar restrictions on power bank use in the cabin after their own incidents.

The practical version of these rules is worth adopting even on airlines that don't enforce it: keep your power bank with you rather than in the overhead bin, avoid cheap or visibly damaged chargers, and tell a flight attendant immediately if a device ever feels unusually hot — rather than waiting to see what happens.

Putting this in perspective

What makes a story like this feel frightening is the setting, not the actual danger. A battery issue at home is background noise; the same issue at 35,000 feet feels like it has nowhere to go. But the aircraft did have somewhere to go, the crew had the training and equipment to handle it, and the flight ended exactly how it was supposed to: safely, with everyone walking off. That gap, between how a story feels and what it actually involved, is most of what flight anxiety runs on.

If sudden, unfamiliar moments on board are the part of flying that gets to you most, having something concrete to open in that moment tends to help more than trying to push the thought away. Our Flight Mode guide is built for exactly that: short, quick-access sections you can find in seconds when something unexpected happens, rather than a long read that needs calm nerves to get through.

Frequently asked questions

Can a phone or power bank really catch fire on a plane?

Yes, occasionally — the FAA recorded 93 such incidents across US flights in 2025. It's a known, trained-for risk rather than a hidden one, and the vast majority of flights never encounter it.

What do flight crews actually do if a battery starts to smoke?

They're trained to cool the device, usually with water, since a standard extinguisher stops the visible flame but not the underlying chemical reaction. Many carriers also carry fire-resistant gloves and containment bags as backup equipment.

Why did the IndiGo flight divert if the fire was already out?

Diverting after any onboard fire event is a standard precaution, not a sign the aircraft was still in danger. It gets the aircraft and anyone affected checked on the ground quickly, rather than continuing on to the original destination.

What can I actually do to reduce this risk when I fly?

Keep power banks and spare batteries in your carry-on within reach rather than in the overhead bin, avoid damaged or off-brand chargers, and tell a flight attendant right away if a device ever feels unusually warm.
