I doubt they'd refuse your card, but sounds like they'd price it from your home country. I also recall in one of the several threads that someone did show up and couldn't get past the first desk.
I'm kinda stymied for now. Gardyloo posted over on the Premium Fares thread (Mileage running forum) about pricing a DONE4 out of JNB, avoiding BA and their fees. How that was accomplished, I know not, and I don't think it was actually purchased. It's a nice trip, and I'd go that way, but want to meet friends in Budapest after my meeting. I finally called Qatar today since they don't play on the oneworld tool. They told me to submit my route to
[email protected]. He spelled it out phonetically, oscar, november, echo, whiskey....Still, didn't work, returned undelivered. I have another addy, and if it doesn't work, I guess I'll call again and read it off over the phone.
I'm planning to submit this:
CPT-DOH-BUD-LHR-DOH-LAX-JFK-DFW-ANC-DFW-JFK-HGK-KTM-KUL-MLE-HKG-JNB
But Mileage Monkey says it's invalid.

Probably something obvious. I need to take up a simpler hobby, like quantum physics.
