It's really not even about the cost of fuel. With aviation it's all about maintenance costs. Electric aircraft will be orders of magnitude simpler and cheaper to maintain than jet turbines. This is what will unlock cost effective small scale commuter routes, allowing you to just hop on a small 10 passenger plane at a neighborhood airport and take a 300 mile flight with no need for security.
