The Messerschmitt M 24, otherwise known as the BFW M.24, was an airliner developed in Germany in the late 1920s^[1] as a further development in the series of designs produced by Messerschmitt, based on the M 18.^[2] Like the M 18 and its follow-on, the M 20, it was a high-wing cantilever monoplane with a fully enclosed cabin and fixed tailwheel undercarriage. It was slightly smaller than the M 20, seating only eight passengers instead of the ten that could be carried by the previous aircraft.^[2]

Two prototypes were initially built with BMW and Junkers inline engines, followed by two more with BMW-built Pratt & Whitney radials. However, Messerschmitt proved unable to sell the design, possibly due at least in part to the enmity of Deutsche Luft Hansa director Erhard Milch towards Messerschmitt.^[3]

The first M 24a (Junkers-engined, registered D-1767) was used commercially from 1930 by Nordbayerische Verkersflug on the Dresden-Chemnitz-Plauen-Nuremberg route, until it was lost in 1934.^[4]
