Well, I hope they last...at least for a while...I jumped for 4 of those tickets to fly JNB-DUR in November...makes it cheaper for me to fly from GRJ to JNB with Kulula and then Interlink to DUR, than direct SA to DUR.
They're not currently flying the flights to Kruger, Maputo, Pemba and Polokwane, but have these on their website though, so probably hoping to relaunch it later again. They've never flown to the Garden Route (GRJ, Plett or PLZ), but have advertised a CPT-GRJ-Plett-PLZ route last year, but nothing happened of it, maybe still in the pipeline. Wouldn't be surprised then if they maybe start weekend flights JNB-GRJ as well.
BUT, ofcourse will they make it? 6 737-200s, ok say 3 operational at the moment, doing only 4 roundtrips a week, Fridays and Sundays simultaneously. So what does the other aircraft do, or what do they all do the rest of the week?
