An Air China flight diverted after a fire broke out in the overhead bin. Fortunately there were no injuries, but one certainly wonders when an incident like this will have catastrophic implications.
Overhead bin fire causes chaos on Air China flight
This incident happened today (October 18, 2025), and involves Air China flight CA139, scheduled to operate from Hangzhou (HGH) to Seoul Incheon (ICN). The planned 607-mile flight was operated by an eight year old Airbus A321 with the registration code B-8583.
The plane took off at 9:47AM local time, and climbed up to its cruising altitude of 33,000 feet. However, once at cruise, a battery stowed in a passenger’s carry-on bag caught fire. We’re not just talking about a little bit of smoke, but a full blown fire with big flames and black smoke.
The crew managed to contain the fire, and the flight diverted to Shanghai (PVG), located just 103 miles from Hangzhou. The plane landed there at 11:05AM local time, 1hr18min after it first departed. The airline ended up rebooking passengers on another Airbus A321, with the registration code B-6883, and passengers traveled to their destination with a delay of around five hours.
Here’s the statement that Air China issued regarding the incident:
“A lithium battery spontaneously ignited in a passenger’s carry-on luggage stored in the overhead bin on flight CA139. The crew immediately handled the situation according to procedures, and no one was injured.”
The video footage of the incident is kind of wild.
Thermal runaway incidents are a big problem for airlines
Unfortunately incidents like this are no longer super rare (though the extent to which the fire spread here was a little more than what you’ll usually see). Lithium ion batteries are at risk of thermal runaway incidents, which is why travelers are always asked at check-in to confirm that they don’t have any lithium ion batteries in their checked bags.
While you never want a fire on a plane, it’s much easier to contain in the cabin than in the cargo hold. In the cabin, crews are trained on how to deal with these kinds of situations, and they have the tools needed to put out and contain fires.
What’s much more concerning is what would happen in the event that an incident like this happened in the cargo hold, which the crew wouldn’t have the ability to put out. I hate to be grim, but we’ve now seen a countless number of thermal runaway incidents in the cabins of aircraft. Sooner or later, aren’t we going to see one of these happen in the cargo hold? It’s certainly a scary thought…
Bottom line
An Air China flight today diverted to Shanghai after a lithium ion battery in the overhead bin caught fire. Fortunately the crew managed to contain the fire, and there were no injuries. These kinds of fires are becoming an increasingly big problem for airlines. Fortunately up until now, they’ve always involved batteries in the cabin. A fire like this in the cargo hold could have very different implications…
