> There isn't really an alternative for jet fuel, is there?

But in many cases there is an alternative to air travel, at least for short distances. I don't really understand why railways (at least in the UK) such ridiculously expensive. Return flights from London to Edinburgh start at £30, train tickets between the same cities start at £100. A return ticket from a station in 50 miles from London is more than £65 (peak times).
