My experience as a first time Flyer wasfinr except that both times when I flew to Frankfurt and also back to ORTambo my baggage go delayed. That was a bit of an awkward experience. Inve I can understand but twice I knew that I used connecting flights but who that happened to my my bag is really a bit out of the ordinary Although I must say the service to found my bag in Frankfurt was really excellent. Now I am waiting for my baggage to be send to my home airport Bram Fiacher in Bloemfontein. Hope I get it also so soon.
