Jet Blue Tweets Discount Air Fares - New Promotion Approach

Jet Blue and United have starting using Twitter for discount air fare promotions. This is an interesting test of an approach to generate marketing ROI from Twitter. As reported in this USA Today article, Jet Blue is sending out Tweets, typically on Mondays, announcing reduced airfares on unsold seats. The trick is that followers must react quickly to capture these discounted rates. (By the way, love the name "Cheeps" even though it may be too downscale and may cheapen the brand equity.) A recent tweet offered a $9 fare from JFK to Nantucket. It's a hihgly targeted approach to fill underutilized and expiring capacity by offering these discounts to a limited audience without widespread exposure to the rest of the market. There's always a new wrinkle for brand marketers... If you are small business, how might you use this approach to promote your brand in your local market?
