Many 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.
