Booked in early January for Oct/Nov 2 x J IST-CPT/JNB-IST-ASR-IST as part of a *A trip to ZA. Needed to work it a bit, but lots available.
No TK via YYZ, some AC, but no domestic J to YYZ. Even Y to YYZ is Clasic+ for most of 2013.
Never found LH or SA in J for a 2 month window to ZA. Did find SA via EZE and GRU though.
