The demonstration flight is planned for the second half of 2008 using an Air New Zealand Boeing 747-400 equipped with Rolls-Royce engines. Boeing is in discussions with fuel-source providers around the globe to identify potential biofuels that are available in suitable quantities for laboratory and jet-engine performance testing and in compliance with stringent aviation requirements. Additional details will be announced closer to the actual demonstration flight date.

"This test flight is another step in our plan to lead the globe in development of the most environmentally responsible airline," said Air New Zealand Chief Executive Officer Rob Fyfe. "We have already taken large steps toward this goal by introducing fuel-efficient Boeing 777s and we eagerly await the first of our 787-9 Dreamliners which will burn 20 percent less fuel than the planes they replace."

Boeing 787 Dreamliner should go into service in 2008 too.
