Flight crews and their passengers will be affected by a proposal from the Departments of State and Homeland Security to require a U.S. or foreign passport when traveling between the U.S. and other countries in the Western Hemisphere. Starting January 1 next year, a passport would be required for air and sea travel to and from Bermuda, the Caribbean and South America. Effective Jan. 1, 2007, the requirement would apply when traveling by air or sea to and from Mexico and Canada. By Jan. 1, 2008, travel by land to and from Mexico and Canada would be included in the required new documentation.
