The routing itself is fine - both Africa and Europe are in Area 2. I still don't know why they have the continents specified in the rules as there are no restrictions or requirements for "inter-continental travel". Unless there is a fare from one country that requires it.
Just have to worry about mileages and the other peripheral rules like stopover lengths etc.

Cheers.
(Oh - and nicely done too btw. This thread finally gets us past the total of oneworld threads/topics!!)
