i wish, batteries are still too heavy to replace jet fuel, hydrogen could work weight wise, but too low density and you just don't have space in an airplane (you could design one but it'll be too big and have too much drag).
best possibility for now is biofuels. basically plug and play.
better yet, replace all major overland routes with high speed rail, much cheaper than flying anyways.
Sail boats work great.
