My other concern is that the JNB-CPT-JNB portion of my trip (SAA, added to my DL reservation by a DL phone agent) is still missing from the web.

It was there, as part of my online intinerary, for two weeks, but disappeared yesterday.

I still have it on a paper ticket, but of course, the whole reason for putting it all in one reservation was to oblige Delta and SAA to get me to my destination should one of the flights be late.

Will my paper itinerary suffice in that regard? Or are they going to pull up the itinerary on the computer and tell me I'm screwed?

I think I'll call SAA this morning and try to confirm that part.
