BA CityFlyer is a wholly owned subsidiary airline of British Airways with its head office in Didsbury, Manchester, England. It operates a network of domestic and European services from its main base at London City Airport. All services operate with BA's full colours, titles, and flight numbers.
BA Cityflyer Limited holds a United Kingdom Civil Aviation Authority Type A Operating Licence, it is permitted to carry passengers, cargo and mail on aircraft with 20 or more seats.
British Airways' sale of BA Connect to Flybe in 2007 did not include the London City Airport operations and its associated fleet of ten Avro RJ100 regional jet aircraft. This led to British Airways' decision to resurrect erstwhile Gatwick-based CityFlyer Express (which BA had integrated into its Gatwick mainline short-haul operation in 2001 following the acquisition of CityFlyer Express in 1999) as a new wholly owned subsidiary to take over this operation, as of March 2007. BA CityFlyer was awarded an Air Operators Certificate on 8 February 2007, and started operations on 25 March 2007.
