SOUTH African Airways has recommended US-based Boeing as the supplier of 20 to 25 new planes in a possible deal worth R4,3-billion, a senior government official said on Friday. The official said the recommendation is, however, still subject to final approval by South Africa’s transport utility Transnet which owns 80% of SAA. SAA Chairman Mafika Mkwanazi said on Thursday a formal public announcement was likely to be made next Tuesday after all SAA shareholders have considered the deal.
