Air Namibia (SW) is looking for replacements of its three units strong (leased) B737-200 fleet. Visit to Airbus in Toulouse/Hamburg (?) has already been paid. Of special attraction seems to be the CCC between the A32X/343. Not clear yet if new frames will be ordered, leased in, or the lease contracts of the 732s extended. Source is Allgemeine Zeitung Namibia.
I tend to say that we will see Air Namibia ordering 3 A318 or A319, possibly 4, all leased. Boeing still has a chance, but I'd say that at SW the Cross Crew Commonality could indeed make sense and safe quite some money. IMO chances 50% Airbus, 30% Boeing, 20% current leases are extended.
