Very peculiar. You say a LONE4, but then you are following more of a Global Explorer type of itinerary including limiting yourself to 26,000 miles. I expect it's the latter so that's what I will assume.

First, Air France is not a Oneworld partner, or did you mean QF?

Second, if it is in fact a Global Explorer, you can only have five stopovers and only two per "region". The rules more or less define a "region" as a continent

If my assumption is wrong and this is in fact a LONE4, then you can't use FJ (or AF). So you might want to clarify what youre trying to do.
