I just finished an ex-JNB AONE4. I booked just 4 segments, wanting to get it booked and willing to pay $125 to change it later. I booked it entirely with the Capetown AA rep, including pricing and ticketing (the rate desk didn't respond to them within a few days so the agent priced it himself, within a few dollars of what I expected. They're competent and quick, although I was on hold for a few minutes a couple of times.

En-route I made changes with the desk at DFW several times, and I believe they never ever calculated taxes and fees correctly. I'm about to sit down and calculate the correct fare and get my money back directly or via due process, but every interface with them that involved the rate desk was tedious and painful.

(how in this day and age can an international call to a first- or second-world country cost anything? Isn't everyone using ooma or some voip service? )
