No, you want to compare likely transportation alternatives. If you're going to go on vacation, a likely decision you'll face is whether to pay for airline tickets and fly, or pay for fuel (and possible rental) and drive.
That's all well and good, but while you're making decisions, you'll also have to decide where you're going on that vacation. Maybe you decide to drive a couple of hundred miles, or maybe you decide to fly to Hawaii.
These things don't happen in a vacuum -- well at least until the space plane becomes a reality -- so while it's entirely possible that, given the current infrastructure, if I want to get from point A to point B, flying may be more environmentally friendly, that's a marginal case. If all the planes disappeared tomorrow, what would that do to our energy consumption?
