I hereby break the news that Ghana Airways and Nigeria Airways have both ceased operations. This caused me a whole bunch of sadness, not merely because neither of them were yet on my "taken 'em" list, but because they each had history and heritage, as descendants of ye olde West African Airways Corporation.
There's probably a bunch of other African carriers that descended from colonists' airline networks and today are no longer; and Africa doesn't seem to lack for LCC-style up-and-comers, like InterAir and, well, I don't like their name, but Mango. (Mango? Why is the airline named after a silly-sounding fruit? Are we FIGHTING stereotypes about Africa with a name like this, or what? What is the deal?)
So which African-type airline operating today has the richest history behind it? The initially tempting answer is SA, since they're so big, but I think you gotta give big ups to KQ (The Pride Of Africa!) and the non-sub-Saharan fellas, like AT and Egpytair (I do not know Egyptair's IATA code offhand, sorry).
My favorite African aviators are lilac-breasted rollers, but that's a bit off-topic.
