Enough connection time in JNB for customs/immigration? (ORD-DUR, via GRU & JNB)
I'll be flying from ORD to Durban on SAA (connecting in GRU and Johannesburg). I understand I'll have to go through customs/immigration at JNB (and not in DUR) since it's my first arrival point in South Africa.
My proposed connection time at JNB is 1hr 20 min. One agent told me it's too little and another said it's fine. Anybody with experience on this transfer have any tips? Will it be enough? (Full itinerary will be on one ticket through United using miles; next option is 4 1/2 hr layover at JNB)
Thanks.
