http://www.gcmap.com/mapui?P=ATL-JNB http://www.gcmap.com/mapui?P=ATL-JNB The nearest non-final destination for almost the entire flight is (a) pretty far away from the flight path anyway (b) probably not on anyones list of places they'd hope to end up in a severe medical emergency.

Wow, that path looks like it avoids any kind of land on purpose. Might make sense for legal issues, but I'd be much more comfortable if it went partly over South America or Africa (or close to the shore) in case of trouble with the plane.

  That path is a great circle path, it's simply the shortest path across the face of the earth. It's not a flight plan or anything (but, being the shortest path, it's pretty close to what any given flight would follow). http://www.gcmap.com/faq/intro#definegc http://www.gcmap.com/faq/intro#definegc Also, because it's so far from land, there are special procedures that need to be in place, see eg. ETOPS.

  There are actually regulations about how far an airplane can be from land - it's why so many flight paths are similar (US-Scotland overlaps US-Paris, for example). You can use this website to see the true flight path for the Johannessburg flight: http://dl.fltmaps.com/en http://dl.fltmaps.com/en [enter Atlanta and Johannesburg as the endpoints] EDIT: Can't find an FAA source about distances to airport, but here's a related Wikipedia page. https://en.wikipedia.org/wiki/ETOPS https://en.wikipedia.org/wiki/ETOPS

    That map does not show true flight paths, those are heavily stylised. This is a true flight path, and it's much closer to the great circle: https://www.flightradar24.com/DAL200/ae190b1 https://www.flightradar24.com/DAL200/ae190b1

      You're right - I didn't realize those maps were stylized. Thanks for the correction!
