Cape Town - South African airways spokesperson Tlali Tlali has confirmed the national carrier will discontinue its own operated flights to Buenos Aires on the 28th of March. The direct route cut forms part of its 20-year turn-around strategy where unprofitable routes are being assessed and axed where necessary. The airline said it is embarking on a number of codeshare agreements in order to extend its network without having to invest in more aircraft - especially since Public Enterprises Minister Malusi Gigaba ordered the airline’s management team to withdraw its tender for more fuel-efficient long-haul airplanes - a proposal deal that would have seen the airline fork out an estimate R60bn for 23 new wide-body, long-haul aircraft.In order to service the route lag created by the Buenos Aires cut, South African Airways and TAM Airlines, one of the largest carriers in South America, have implemented a codeshare agreement. The codeshare for the route between Sao Paulo and Johannesburg with 11 flights per week, took effect in September 2013.SAA also recently announced that it is resuming its non-stop flights between OR Tambo International - Johannesburg and JFK International Airport - New York. on 9 March.
