Is this with Saudia (SV)? I already bought my Air France Premium Economy ticket, but I would have been glad to do SV again. Only thing to keep in mind now is the British foreign affairs ministry have just issued a warning about Tunisia. Apparently there is a lot of civil unrest brewing (especially in the city of Sfax) and the situation could change very quickly.

ETA - I see from the link above that this is indeed with SV, but there appears to be no availability in July.
