Vick has an endorsement deal with Airtran, which has it's main hub here in Atlanta. So does Warrick Dunn, Ilya Kovalchuck and I think Kari Lehtonen. They're on billboards all over town.
There was a blurb in the paper recently about the way AirTran was signing individual athletes in markets they serve to endorsement deals. Most pro teams have deals with airlines. Rather than outbid the mega airlines, AirTran has been picking & choosing individual athletes to pimp their flights.
And I certainly wouldn't knock AirTran as an airline. They've been steadily expanding and taking it to the big airlines. If you live in Atlanta, Airtran is an outstanding alternative to the monster that is Delta. Here's a url to their route map. Click on Atlanta & you'll see they do a heck of a job serving this market. Now that they've partnered with Frontier Airlines, they have a lot more offerings out west.
Also, keep in mind that the Atlanta market isn't served by Southwest. Back in the day, the politicians and business folks here made it clear as day that they didn't want Southwest competing in the Atlanta market with hometown Delta. So if I want to catch a flight on Southwest, I have to drive to Birmingham which is 2 hours away. Without Southwest around in Atlanta, the competition from little old Airtran has helped bring Delta to it's knees.
Edit: As a consumer, I love the idea of competition in the market place and the innovation it brings. However, Delta's woes, which are largely self-inflicted IMO, have a huge potential to put a hurt on the metro economy. If the US Airways bid goes through, the potential exists for a lot of jobs to go away. Of course, it would also open up a ton of gate capacity at the airport, allowing for folks like Airtran, JetBlue, or Southwest to expand.
