Tomorrow AirTran is unveiling a new look on one of its planes that will have a familiar theme for Baltimore football fans. The "Ravens One" is to feature "custom aircraft livery" in Ravens colors. A purple plane? That's my guess. (And considering the weather forecast for Tuesday, could be a purple plane in the rain. But I digress.)

Baltimore's not first for the new football-themed look from AirTran. In late August, they unveiled an Atlanta Falcons jet (above). And I've read that the Indianapolis Colts are getting one too. (if they haven't already). AirTran is the official carrier of the Falcons, Ravens and Colts. I didn't know that, but now it all makes sense. A few years ago, US Airways painted on a Steelers-theme on one of its planes and they also have jets with Eagles, Cardinals and Panthers logos. (Wonder how the NY Jets feel about all this?)

But it's not just a flying football kind of thing. Southwest has been making art out of their fuselage for years - they were definitely the first to catch my attention with themes including Shamu, the SeaWorld star; 'Maryland One,' featuring the colors of the state flag; and then the top model theme earlier this year featuring the Sports Illustrated swimsuit model Bar Rafaeli. And they have many others, too.

So AirTran's a little late from the gate, but they get credit for making tomorrow's unveiling as much about charity as it is about a change of paint. The airline will donate $10,000 to Franklin Square Hospital as part of the event. Green - it's my favorite color.
