I think Oneworld should consider finding an African member, because we lack coverage in Africa.
There are 3 options which should be considered:
-Royal Air Maroc, no A+ service level and no advantage of a Casablanca hub vs MAD, but already existing routes into Africa.
-Expansion of Iberia into west-africa (

-Start own carrier in Africa, but very risky given political barriers and safety issues.
My utopic view is:
Purchase of AZ by IAG and expansion into Africa and the Middle East
