Several years ago, I made a paid business RTW booked with AF.
ON LIM-ATL-SFO-HNL, with Delta, I was in J only on LIM-ATL (international flight)
2 other legs were in Y...as there were no J but only F on DL domestic flights
On SFO-HNL I paid USD100 (it is a RTW rule in that case) to be in F.
IMHO, AF does not sold yet F RTW
