Taking fuel efficient flying seriously

It's interesting to see that soaring fuel costs are leading to jets being flown a bit slower, in order to increase fuel efficiency.

But, for the short inter-city hops in Australia, why don't airlines seriously consider going back to modern turbo-prop aircraft? According to to The Times last month:
“Propeller-driven planes achieve massive fuel benefits on shorter journeys,” Kapil Kaul, of the Centre for Asia Pacific Aviation, said.

For a trip of less than 600 nautical miles, or about 90 minutes’ flying time, a turboprob may use as much as 70 per cent less fuel than a similar-sized jet, he said.

According to Treehugger, the environmentalist website, travelling on an aircraft such as a Bombardier Q400, one of the most advanced turboprops, can be more environmentally friendly than going by car (but not quite as green as taking a train).

This post makes the same point.

Of course, such fuel efficiency doesn't hurt from a greenhouse gas point of view, but even if you are a complete skeptic on that, the economics still make a lot of sense.
