In a statement, CEO Nico Bezuidenhout said the route was one of many planned for the next year-and-a-half, "with a focus on the east African seaboard".
"There is a requirement for a low-cost carrier on the Johannesburg-Port Elizabeth and Cape Town-Port Elizabeth route and, with the recent exit of capacity, Mango has brought forward its plans by a few months in order to accommodate market demand," Bezuidenhout said.
Earlier this month 1time airline, which flew the Johannesburg-Port Elizabeth, route applied to suspend its services and filed for termination of business.
Bookings are available on the new routes at an inaugural fare of R599 between Johannesburg and Port Elizabeth, and R699 between Cape Town and Port Elizabeth.
