Would not get too excited, if history is anything to go by these operations never take off- this type of thing noramlly only comes off if an established operator gives it a go- like CE to LGW. I cant see the SA DOT taking another chance like they did with Civair and African Star, what was the last one to try Cantuan or something?
Also the aircraft types chosen- a 340-500 and a 777 just gives one the impression that this is more a pipe dream than a real possibility.
I just hope they dont go recruiting crew with emtpy promises and that potential employees only sign on once they have actually clapped eyes on the operating licence and seen the aircraft out on the ramp.
