In 2010, when QF still handled the online ticketing for JL, I booked an exNRT DONE3 using both a +61 phone number and AU based card.

QF Tokyo had issues charging the card (default daily transaction limits the bank had never told me about) and asked QF Sydney to call me. Between public holidays in Japan, work in CBR and some back and fourth between the bank and QF SYD, it took about a week before everything was sorted out and the transaction authority went through.

I was charged the Japan price despite QF knowing full well that I was in CBR at the time. The only cost issue was forex changes between AUD and JPY between the time it was ticketed and QF finally decided to take the money out. (having a QF issued DAS13 in the system at the time as positioning flights may have helped, but I doubt it)

This year, I had a CX issued exICN DONE3. Again I had an AU phone number and credit card in the booking. No issues and was charged the Korean price. Would have done the same last year, but the tool kept falling and had to book via agent in Canada.


In 2009, I booked an LONE4 (my last before starting to use DONEx's ) out of CBR with the online tool. I used an AA codeshare on a QF CBR-SYD flight so AA would ticket. I was also able to book an AS flight LAX-PDX using the QF code.
CBR-xSYD-xLAX-PDX-DFW-DEN-xDFW-BOS-xMIA-ATL-LHR-xSIN-KUL-NRT-KIX-xSIN-xMEL-CBR
I was keeping track of the changes as they happened (such as AA canning the DEN-xORD-BOS direct and rerouting me via DFW and forcing a 17 sector ticket). Technically I shouldn't have been able to book CBR-SYD on the AA code without also booking QF11 on the AA code, and I shouldn't have been able to book the LAX-PDX at all.
A few weeks out, AA BNE called me to go over the changes (which I already knew about). Only then did they notice the AS operated flight. After checking with Dallas, they let me keep it as it had gotten through and the ticket issued.
