in may 2015, "the wall street journal" reported that bombardier was considering marketing a cs500 aircraft, being further stretched than the cs300, to compete with the standard 160- to 180-seat versions of the boeing 737 and a320 airliners. however, development has not yet been committed. the existing wing would be capable of supporting a stretched version. in january 2019, airbus hinted that a larger variant could be developed, owing to ramped-up production and market demand for the currently-produced models. an acj version of the a220 was also mentioned as a possibility. however, in june 2019, airbus indicated that it would not consider launching an a220-500 until it has solved its a220 productivity issues, and definitely not in the following 12 months. speculation about a stretched variant continued in november 2019, with air france mentioning an a220-500 during an investor briefing on its modernisation strategy.
