The first was powered by 347 kW (465 hp) Bristol Jupiter VI radial engines and the second, an improved model, the F.XIIM, was about 20 km/h (12 mph) faster than the Dutch-built F.XIIs.

Ten aircraft were ordered by KLM/KNILM for operation on the Amsterdam to Batavia route.

[1] In 1936 KLM sold four of the aircraft to the British Crilly Airways to operate between London and Madrid, this didn't get the support of the Spanish government and the aircraft were passed to British Airways for use on European routes to Paris and Scandinavia.

[1] They were soon considered obsolete by British Airways and sold with some ending up with Spanish Nationalists for use in the civil war.

[1] Two of KLMs remaining F.XIIs were sold to British Airways and one to a company in French West Africa but ended up in Spanish Republican hands.
