The F.III was first used by
KLM when they reopened their
Amsterdam-
London service on 14 April 1921 (they did not, at this time operate over winter). Soon, F.IIIs were also flying on routes to
Bremen,
Brussels,
Hamburg, and
Paris. They proved to be very reliable aircraft.
KLM received 14 F.IIIs from Fokker's German factory at
Schwerin during 1921 and built two more itself from spares in the following year. This final pair used
Rolls-Royce Eagle VIII engines, with the pilot on the left. Another operator of new F.IIIs was
Deutsch-Russiche Luftverkehrs Gesellschaft (
Deruluft) which used nine aircraft on their
Berlin-
Königsberg-
Moscow route from May 1922. These machines, partially built in
Schwerin and finished in the Netherlands at
Veere, had Eagle engines. One was a Fokker-Grulich.
Deutsche Aero Lloyd gained a licence to build F.IIIs as they had for
F.IIs and the company, with its southern subsidiary built and operated 18 of these Fokker-Grulich F.IIIs. Most of these used BMW engines, typically the
BMW IV in preference to the
BMW IIIa. Some of these were re-engined with the
BMW Va, and were designated F.IIIc. Another operator from new was the Hungarian airline
Malert, which received six Dutch-built aircraft for their
Budapest-
Vienna-
Belgrade service from 1922 to 1929. These initially had BMW IIIa engines, but later ran with
Breitfeld & Daněk Hiero IV engines. They had larger wings, increased in area by about 14%.
Deutsche Luft-Reederei also operated two, originally intended for KLM. Four F.IIIs probably went to the
United States. Later F.IIIs changed ownership frequently as airlines went bankrupt or merged. They were still flying commercially in Germany until about 1936. ==Accidents and incidents==
