Hi there,
Yes - I had also heard that for BA CPT and JNB are just 'cash cows' - CPT has been very strong hence the increase in capacity. I suspect that this will increase BA's stronghold on the SA market even further and that VS will also suffer a bit in JNB. Given the huge market that BA makes work really well I would not be surprised if JNB gets up to double daily A380's and CPT is double daily 747-400's all year with a bit of extra 777-200 for peak season.....
