No, we use Servisair (who are actually very good indeed).
It is a bit unfortunate that we use the AF-liveried aircraft sometimes at LCY. They were all originally painted for franchise routes, but find themselves on other routes from time to time as the ops plan changes. With Citijet in the same livery, it gets confusing.
Hopefully that will be a thing of the past when the new RJX arrives...
