Ya but East Africa could be very tricky as most of those countries have pretty low income and some aren't even open to foreign airlines. It could be a pretty risky market what about expand a bit more in Europe? I think some European countries might be good targets? Hmm i dunno Europe that well as I pretty much skip France and Germany. Any ideas? Alliance friends?
I'll give Germany a bit of a go then, it is the country where I started after all!
As Patson said, Africa is very low income.
I have try setup route from Morocco to the eastern Africa, but it keep losing money.
I have setup hub in USA and create large demand, and the route is better now.
Nigeria and Egypt are the best option for you to setup hub,
but the Reputation point for Egypt is too low.
South America countries have more Reputation points than Africa.
But I think you can consider one of the Northern European countries, and setup a route to west coast.
You should able to create a route with few thousand passengers.
and a first or second place of these countries should give you enough points to the next level.
