Battery swapping didn’t make sense for electric cars because the battery itself constituted so much of the cost of an electric car. It’s cheaper to buy two electric cars than to buy one + a spare battery, taking into account the labour cost of performing frequent battery swaps. I’d guess similar economics applies to electric planes, although I admittedly don’t have a strong source to cite.
