I had thought it was just an issue of LA not yet publishing domestic schedules, but this makes a bit more sense.
Looks like we'll have to rethink a bit - any other suggestions of places to go in South America? We've done Peru before and wanted to do something outside of cities. Were also looking at Bariloche, though I know the weather's not great that time of year and I think it creates the same EZE//AEP problem.

Also, just to be thick on the South Africa issue - would we be able to fly LHR-NBO as our final leg or have to do LHR-NBO-JNB? If our last leg ended in NBO, could we still buy in South Africa.
