JetBlue has signed a multi-year deal to become the official airline of the Boston Celtics. The five-year partnership launches with a fan sweepstakes, Top 5 Plays of the Week feature on Celtics.com and a number of shared community initiatives that will impact local youth and the environment. To celebrate, JetBlue and the Celtics are giving one lucky sweepstakes winner and guest the opportunity to follow the Celtics west to San Francisco on JetBlue's new Mint service.

Keep an eye out on Celtics.com for your chance to enter starting in early February. JetBlue and the Celtics will also team up for the environment through "D" for Trees program where a tree will be donated to a local Boston green initiative for each steal or block during regular season home games. JetBlue's partnership will include joint marketing promotions and advertising.

Elements will include online advertising, e-mail marketing and Celtics.com video features, as well as contests, and giveaways for Celtics fans.
