CityFlyer Express was a short-haul regional airline with its head office in the Iain Stewart Centre next to London Gatwick Airport in England. In 1993 it became the first British Airways (BA) franchisee operating as British Airways Express. CityFlyer's ownership passed to BA in 1999 when that company bought out the original promoters as well as 3i, the airline's main shareholder at the time. Initially, CityFlyer continued to operate as a separate unit, but it was eventually absorbed into British Airways' mainline short haul operation at Gatwick in 2001, the result of a change in British Airways' strategy for its Gatwick operation.
