Its home base was the former Hahn US military air base (now Frankfurt-Hahn Airport), from which the company's name originates. In 1997, Hahn Air joined its first Billing and Settlement Plan (BSP) in Germany. The airline has the 2 letter code HR and the invoice number (IATA prefix code) 169. Hahn Air flights have been sold via the Amadeus computer reservation system since 1999. That same year the first agreements were signed with airlines from Latin America, namely Aerolíneas Argentinas, Avianca, LAN Airlines and Varig, which formed the foundation for the ticketing platform. In 2001, Hahn Air became an IATA member and joined BSPs including France, the United Kingdom and Spain. Hahn Air also joined the Sabre, Galileo and Worldspan computer reservation systems. Further BSP memberships were concluded and, in 2003, the company's headquarters moved from Hahn to Dreieich, near Frankfurt am Main. One year later, Hahn Air became a member of the Airlines Reporting Corporation in the US and is represented together with its partners in the Abacus computer reservation system. The company's 100th interline agreement was also signed that year. In 2006, Hahn Air issued its first e-ticket and its first interline e-ticket on its computer reservation system. The same year, Hahn Air Systems was founded and offers Computer Reservation Services (CRS). The Hahn Air flight operations went through IOSA certification for the first time in 2007. The same year, Hahn Air entered the Japanese and Korean markets by connecting to the Axess, Infini and Topas reservation systems.
