routeings from the gulf to fajs?

[captain cumulonimbus]

hi all.

flying quite often between fajs and omdb,as well as to bahrain,i've noticed a track overflying DV VOR at Dar es Salaam is taken.Now flight time is around 4h20 for that as you leave SA airspace at GWV.Flights directly to DAR exit it at EPSEK (way off to the east of GWV) and arrive overhead DAR with a flight time of only about 3h40.Why take the much longer route that passes near Harare as opposed to a much more direct one?

Checked the Jepp and the shorted route seems much more sensible.Anyone fly this route and know why?

Also,is there a lot of traffic on 126.9 up that way?

Cheers,Cb

We do normally fly via Epsek to DV but if you where on a flight that route via GWV to DV, the most likely reason is that the dispatch guys optimise or routing with refrence to cost and try to avoid any serious areas of turbulence ( In theory),Also there could have been an airway closure for some reason through Moz (AWA).
THe only real conflicting 126.9 traffic,is crossing traffiic between Africa and India and Europe and the Indian Ocean Islands
