Who says Marshall-BWI doesn't have international destinations? (Look for this to get yanked if the Republicans regain the White House in 2012 and the Castros are still alive.) From the airport:

U.S. Customs and Border Protection Approved Airport’s Application for Charter Service Baltimore/Washington International Thurgood Marshall Airport (BWI Marshall) has received approval from U.S. Customs and Border Protection to handle passenger charter air service to and from Cuba. “We are grateful that the federal government has approved the application for direct charter service between BWI Marshall Airport and Cuba,” said Paul J. Wiedefeld, Executive Director of BWI Marshall. “The authorization can produce expanded access to Cuba for Maryland and the entire National Capital region. This service has the potential to benefit many institutions and organizations throughout our region.” BWI Marshall Airport joins a select list of U.S. airports to offer service to Cuba. Previously, only airports in Miami, New York, and Los Angeles were authorized for Cuba service. In recent days, U.S. Customs and Border Protection has opened Cuba service to several new markets, including BWI Marshall Airport. New federal regulations expand religious, academic, journalistic, and cultural travel between the United States and Cuba. Several additional regulatory and procedural steps need to be completed before the charter service between BWI Marshall and Cuba may commence.
