LEONARD NEILL AIR FREIGHT capacity between East London and Johannesburg will double from the first week of March, but national carrier SAA will still rely on its overland trucking service between the two cities. Discount airline kulula.com will introduce daily flights next month between the two airports, using two new MD82 aircraft. Budget airline 1Time has been flying the same type of aircraft, as well as a DC9 on the route since July last year.
