Right, that's basically the problem, if one wants to travel by air with an ebike without hassle, there's no real option to do so.
There's the Ligo 10X (https://ebikes.ca/product-info/grin-products/ligo10x-battery...) which makes 99Wh battery packs that can be connected together, but otherwise it just seems like rules lawyering.
There really needs to be standardization of battery packs for ebikes instead of proprietary ones, so that one could rent a battery at their destination.
At that point why not just rent the whole bike and not need to bring the large object onto the plane?
