Southwest Airlines (NYSE: LUV) and the Greater Philadelphia Tourism Marketing Corp. have found a common interest: gay and lesbian travelers. Southwest has given the city-chartered nonprofit agency $125,000 to help it extend its "Philadelphia - Get Your History Straight and Your Nightlife Gay" marketing campaign, an award-winning effort to capture some of the $55 billion a year that gay and lesbian travelers say they spend on going out and about. The funding coincides with Southwest's own launch last month of a Web page aimed at this specialty travel market. The GPTMC's campaign is here. - Tom Belden
