Jet fuel prices spark turbo prop comeback

As fuel prices soar to record highs and airlines struggle to maintain profitability, the unglamorous but fuel-efficient turboprop regional airliner is making a remarkable comeback.

The revival of the propeller-driven planes - which typically consume a quarter to a third less fuel than equivalent jets - marks a significant new trend in the industry. Until recently, many commuter airlines had been determined to consign the planes to history and convert to all-jet fleets, which offer greater passenger comfort.

Although the latest generation of turboprops has addressed some of the comfort issues by flying above turbulence and providing quieter cabins, analysts say the airlines' money worries about their bottom line now outweigh any passenger preferences.
