They won't. If you ever flew in these small aircraft, you know that they are extremely susceptible to weather conditions, and can be easily grounded due to rain, snow, strong winds or extremely hot weather. Even ignoring the heavy batteries giving them range that's barely acceptable, you'd still need to pay pilot's salaries per every few passenger, a major cost even when divided between the far larger amount of people flying on an airliner.
