SAN FRANCISCO, April 14, 2012 /PRNewswire/ -- Virgin America, the only California-based airline, is partnering for the fifth consecutive year with the California State Parks Foundation (CSPF) for its 15th Annual Earth Day to support vital environmental restoration and clean-up projects across the state. Virgin America teammates (along with employees from presenting sponsor Pacific Gas and Electric Company) are pitching in today at San Francisco's Candlestick Point State Recreation Area where they are planting native trees, installing new redwood garden boxes and landscaping to help restore and preserve the park. Virgin America teammates in other cities across the country are also participating in local environmental clean-up events throughout Earth month. In addition to Virgin America's efforts on the ground, the airline was the first domestic airline to offer guests the ability to offset their carbon in-flight by using the Red™ seatback touch-screen entertainment system to make a donation to CSPF or to offset the carbon emissions of their flight via the nonprofit Carbonfund.org.

We're pleased to continue our partnership with the CSPF for the fifth year in a row, in order to support their efforts to protect and restore our state's natural resources — especially those in underserved communities like Candlestick Point," said David Cush, President and CEO of Virgin America. Virgin America teammates' efforts at Candlestick Point State Recreation Area will help restore and improve the park's community garden and shoreline. Candlestick Point State Recreation Area is the state's first "urban" park and includes a community garden, open wildlife areas and other public spaces that support a better way of life in the underserved Bay Area neighborhood.
