Pan Am Systems (formerly Guilford Transportation Industries) is a privately held Portsmouth, New Hampshire-based  U.S. corporation composed of rail transport, manufacturing and energy, transportation related brands, and real estate divisions. It formerly held a now-defunct airline division.
Guilford Transportation Industries (GTI) was formed in 1977. GTI entered the railroad business in 1981 with its purchase of the Maine Central Railroad from U.S. Filter Corporation. This was followed by its 1983 purchase of the Boston & Maine Railroad, and in 1984 it purchased the Delaware & Hudson Railway (D&H). In 1988, GTI declared D&H bankrupt. D&H employees took it over, with the New York, Susquehanna & Western Railway managing it. The employees then sold out in 1991 to the Canadian Pacific Railway.
GTI purchased the name, colors, and logo of Pan American World Airways in 1998. In March 2006, GTI changed its name to Pan Am Systems.
- Pan American Airways (1998-2004), a United States airline that operated scheduled services in the eastern USA under the purchased "Pan American Airways" brand, as well as charters for tour operators and services to the Dominican Republic and Puerto Rico. Operations ceased on November 1, 2004, and were transferred to then Guilford Transportation subsidiary Boston-Maine Airways, which resumed service as the Pan Am Clipper Connection brand.
- Boston-Maine Airways/Pan Am Clipper Connection, the formerly certified airline, which operated charter and scheduled passenger airline services between the northeastern United States and Florida and the Caribbean under the Pan Am Clipper Connection brand. In February 2008 the U.S. Department of Transportation proposed the revocation of Boston-Maine's air carrier certification, as it "is not financially fit and does not possess the managerial competence to conduct any air transportation operations and has failed to comply with the regulations governing its operations."  Services ended February 29, 2008.
- Pan Am Services, originally an aircraft service and support center, now a dealer of aircraft spare parts.
