A Laptop Caught Fire on an American Airlines Flight — How Dangerous Are Lithium Batteries at 35,000 Feet?
You’re sitting in your seat as the aircraft begins its approach.
Seat belts are fastened. Tray tables are up. Most passengers are thinking about landing.
Then smoke appears inside the cabin.
Not from an engine.
Not from the aircraft’s electrical system.

But reportedly from something millions of passengers carry onto aircraft every day:
a laptop.
The American Airlines laptop fire is a reminder that the electronic devices we carry every day can become a serious safety issue when something goes wrong with their batteries.
That’s what happened aboard an American Airlines flight from Atlanta to Dallas-Fort Worth on Friday.
And it raises a question every traveller carrying a phone, laptop, tablet or power bank should understand:
How dangerous can a lithium battery become inside an aircraft?
American Airlines Laptop Fire: What Happened on Flight 2398?
American Airlines Flight 2398 was travelling from Atlanta to Dallas-Fort Worth when smoke was reported from a passenger’s device during landing.
According to air traffic control audio reported by CBS News, the pilot reported a cabin fire toward the back of the aircraft while flight attendants worked to contain it.
The pilot also reported that several passengers might have suffered burns.
The aircraft landed safely at Dallas-Fort Worth International Airport.
American Airlines praised the crew’s rapid response in containing the device.
But behind the dramatic incident is a much bigger aviation-safety issue.
CBS News reported that Flight 2398 had 133 people onboard and that one passenger was treated and released after the aircraft landed at Dallas-Fort Worth.
Why Can a Laptop Battery Catch Fire?
Most modern laptops, smartphones, tablets and power banks use lithium-ion batteries.
They’re popular for a reason.
Lithium batteries can store substantial amounts of energy while remaining relatively small and lightweight.
That’s perfect for portable electronics.
But when a lithium battery is damaged, defective, overheated or otherwise compromised, it can potentially enter a dangerous process called:
thermal runaway.
In simple terms, the battery begins generating heat faster than it can release it.
That can lead to:
- rapidly rising temperature
- smoke
- flammable gases
- fire
- neighbouring battery cells overheating
And once that process begins, controlling it can be difficult.
The FAA warns that lithium batteries can produce extreme heat, smoke, fire and flammable gases when they enter thermal runaway.
Why Is This Particularly Serious on an Aircraft?
A laptop fire in your home is dangerous.
A laptop fire at 35,000 feet presents an additional problem.
You cannot simply evacuate the building.
An aircraft cabin is an enclosed environment containing passengers, baggage, electronics and combustible materials.
The crew therefore needs to identify and control the problem quickly.
That’s one reason cabin crews receive training for onboard fire and smoke events.
Passenger safety also extends far beyond seat comfort. See why aircraft seats are critical to flight safety and how cabin design helps protect passengers during emergencies.
And it explains something passengers sometimes misunderstand:
flight attendants aren’t onboard simply to serve drinks and meals.
Their primary role is safety.
When something goes seriously wrong inside the cabin, their training suddenly becomes extremely important.
The Most Important Place for a Lithium Battery May Be the Cabin
There’s another reason aviation authorities place restrictions on lithium batteries.
If a battery begins smoking or overheating in the passenger cabin, somebody may notice it quickly.
Cabin crew can respond.
A battery hidden deep inside checked baggage is much harder to reach.
That’s why passengers should pay close attention to airline rules concerning spare lithium batteries and power banks.
The rules aren’t arbitrary inconvenience.
They’re designed around the consequences of a battery failure.
Your Power Bank Deserves Attention Too
It’s easy to hear about a laptop fire and assume the problem concerns laptops.
It doesn’t.
Many everyday devices use lithium batteries:
- smartphones
- tablets
- cameras
- wireless headphones
- e-cigarettes
- portable chargers
- power banks
- spare camera batteries
That means the small power bank sitting inside your backpack deserves the same respect as a much larger electronic device.
Passengers should always follow their airline’s current battery and baggage requirements before travelling.
What Should You Do If Your Device Starts Getting Hot?
An unusually hot electronic device shouldn’t simply be ignored.
If a laptop, phone or power bank begins:
- becoming abnormally hot
- swelling
- producing smoke
- emitting an unusual smell
- making strange sounds
alert cabin crew immediately.
Don’t wait to see whether the problem disappears.
And don’t improvise your own response when trained crew members are available.
A developing battery problem can escalate quickly.
Early detection gives the crew more time to respond.
Don’t Retrieve a Smoking Device From Somewhere Dangerous
One particularly dangerous scenario can occur when a phone or electronic device falls into the mechanism of an aircraft seat.
Passengers may instinctively try to retrieve it themselves.
But moving an electrically adjustable seat could crush or damage a lithium battery.
If your phone disappears into the seat structure, especially in a premium cabin with electrically operated seats, call a flight attendant rather than moving the seat repeatedly.
It’s a small decision that could prevent a much larger problem.
Should Passengers Be Frightened of Taking Laptops on Planes?
No.
Millions of passengers travel safely with electronic devices.
The lesson from incidents like this isn’t that laptops should suddenly be feared.
It’s that lithium batteries contain significant energy and should be treated properly.
Avoid travelling with obviously damaged or swollen batteries.
Use reputable chargers and power banks.
Protect spare batteries against short circuits.
Follow airline rules.
And if something seems wrong with a device during the flight, tell the crew immediately.

The Bigger Question: Are Battery Incidents Increasing?
The number of electronic devices passengers carry has grown enormously.
A traveller might board today carrying a phone, laptop, tablet, smartwatch, headphones and power bank.
Twenty years ago, that collection would have been unusual.
Today it’s completely normal.
That means aviation isn’t simply dealing with passengers.
It’s increasingly transporting hundreds or potentially thousands of individual battery cells inside a single aircraft cabin.
The overwhelming majority cause no problem whatsoever.
But even a very small failure rate matters when aviation operates millions of flights.
That makes lithium-battery awareness an increasingly important part of passenger safety.
Seat location and design can affect much more than comfort. If you’re choosing where to sit on your next flight, see our complete Best Seats on a Plane guide.
What the American Airlines Incident Reminds Us
The most reassuring part of this incident isn’t that a laptop reportedly caught fire.
It’s what happened next.
The cabin crew responded.
The device was contained.
And the aircraft landed safely.
Aviation safety often works precisely this way.
Passengers tend to notice the dramatic event.
What they don’t always see are the layers of procedures, training and equipment designed to prevent that event from becoming something considerably worse.
So the next time you’re boarding with a laptop and power bank in your bag, there’s no reason to panic.
But there is a reason to pay attention.
Because sometimes one of the smallest objects onboard can create one of the most urgent problems in the cabin.
What Would You Do?
Imagine your phone suddenly became extremely hot halfway across the Atlantic.
Would you recognise it as a potential warning sign?
Or would you assume it was simply working too hard?
Knowing the difference and telling the cabin crew early — could matter far more than most passengers realise.
