In September 2008, Continental announced that it would commence providing seasonal non-stop service between Houston and Rio de Janeiro. The new non-stop flight was timed to provide roundtrip flight connections at Continental's Houston hub to more than 160 cities throughout the U.S., Canada, Central America, Europe, and Asia. Continental renewed its lease for around in Continental Center I. Continental announced that its 4th quarter 2008 net loss widened to $266 million on costs for pilot retirement and reducing the value of its fuel hedges. In January 2009, Continental became the first commercial carrier to successfully demonstrate the use of sustainable biofuel to power an aircraft in North America. During the demonstration flight, Continental's test pilots successfully conducted a number of flight maneuvers, and the biofuel met all performance requirements as compared with traditional jet fuel. The biofuel blend included components derived from algae and jatropha plants, both sustainable, second-generation sources that do not impact food crops or water resources or contribute to deforestation. In March 2009, Continental became the first U.S. carrier to inaugurate scheduled service between New York and Shanghai, China, with daily non-stop flights from the airline's hub at Newark Liberty International Airport.
