I have just quickly scanned the world's busiest domestic airline routes and 2 South African routes are constantly in the top 10, being JNB to CTN and JNB to DBN.
Perhaps those numbers are a little ascewed as it includes a lot of foreign travel but the simple fact remains that there is still a high number of flights taking off and landing between those airports? This is not just amount of flights but also number of seats sold.
South Africa if I remember correctly somwhere in my fanatical search a few years back may even have had the busiest domestic airline travels in the world? I speak under correction as I can't find the figures to back up this claim.
If you consider that South Africa is very much an emerging nation as far as travel is concerned, surely there must be some room to grow for a competitive, well run and efficient low budget airline? (Preferably one not run by the current corrupt government
)
