You piqued my curiosity. The average per-seat fuel efficiency for the major passenger airlines in the U.S. is 59 MPG. If you were traveling as a single occupant in a gas vehicle then it's more fuel efficient to fly. Even two occupants would break even. As far as electric planes are concerned, I don't know much about them. My first thought is airlines would be looking to use them for regional air traffic - where you need to fly from a city that's not one of their hubs to one that is. I'm imagining at this time they're not being considered for trans-national or trans-continental travel - for the same reasons you shouldn't be considering electric vehicles for long road trips.
