alt Hacker NewsMany airlines are going much further than this, for instance Virgin Atlantic ban you from either charging or charging from any power bank, and you can't keep them in the overhead locker, you must keep them next to you in case it starts burning spontaneously!
They have a "fire containment bag" they can chuck it in should you notice it getting hot or smoking.

Crazy thing about these bags is that they're just containment. Once the thermal runaway has started, it's very hard to start as it brings its own oxygen, heat and fuel.
Hence why many places bring a container filled with water to extinguish an EV fire, and then probably send it to a wet shredder to make sure it doesn't re-ignite.
I flew Cathay Pacific late January and power banks were prohibited in both checked luggage and overhead bins. Of course the overhead bin restriction would have been difficult to police and enforce. Also prohibited to use them for charging devices or to be charged from the onboard USB outlets. But the onboard outlets were good enough for anything I needed to do during the 15+ hour flight.
