American Airlines on Sept. 18 will implement "system enhancements" to support additional data collection requirements for the Advance Passenger Information System

, as directed by U.S. Customs and Border Protection. "To facilitate the collection of the required information, all agencies are asked to input a passenger's country of residence into the passenger name record," according to information posted on AA's Web site. "International agencies, including Canadian outlets, should also input the U.S. visiting address for non-resident passengers arriving on flights into the U.S. All visitors to the U.S. are required to provide a full address (street name and number, city, state and zip code) for their first night's accommodation in the U.S." American said travel agencies should refer to global distribution systems for more information.
