Air France is adding eight new routes to its network out of London City Airport.
Five of the new services will be run by its partner CityJet to Geneva, Madrid, Milan Linate, Nice and Zurich.
The other three will be operated by niche carrier ScotAirways to Edinburgh, Dundee and Belfast Harbour Airport.
The new routes are in addition to CityJet's existing services for Air France to Paris Orly and Dublin.
The new routes will open on March 26 and use Avro RJ 85 aircraft seating 95 passengers.
Air France boosting of its London City network follows similar plans by both BA and Lufthansa/Swissair both of whom are increasing their routes out of the London Docklands airport.
Many of the new services by the three major carriers are aimed at capturing the lucrative premium class business out of London City.
The airport which boasts a ten minute check-in time and has won several awards for its services to business travellers, which serves both of London's financial centres in the City itself and at Docklands.
Air France said the frequency of the new CityJet services to the five continental cities will be announced later.
It will codeshare on the UK services with ScotAirways which runs eight flights a day to Edinburgh and four a day to Dundee.
Etienne Rachou, Air France Senior Vice President of Europe and North Africa, said: "We are providing our business clientele with a hitherto unknown service, access to a network straight from the heart of London with all the benefits and services the Air France Group has to offer.
“In this way we are strengthening our position as leader in this market".
