I originally had a DONE4 worked out when 20 segment trips were possible leaving from JNB but then the GFC hit and the aussie nosedived so I had to cancel due to lack of funds with the dollar dropping 40%. Was a sweet 12 month trip too, with PLT challenge I would have ended up with nearly enough AA miles to get a reward ticket around the world a second time in L.
Incidentally I think this was my confirmed ticket I had to cancel:
JNB-HKG-DEL-NRT-PEK//PVG-HKG-JFK-UVF-MIA-MEX-YVR-DFW-LAX-BRU//CAI-MAD-HEL-BUD-xLHR-DAR
*sigh* so many places yet to visit! Luckily the Aussie is strong so I am doing open-ended travelling now.
I am now bouncing around Asia on cheap flights and IMHO it is not worth wasting valuable OWE segments (especially biz filghts) on short Asia puddle jumps when you have so many options like Jetstar, Air Asia, Cebu Pacific and Tiger Airways as well as overland options like Fukuoka Japan to Busan South Korea, South Korea to China overland, deluxe bus from Singapore to KL, etc.
Ican give you my travels as an example: I caught a cheap flight from MEL-NRT on Jetstar for US$200 to get started, at that time I was planning on taking the hydrofoil to South Korea or slow boat to China but I got a cheap Cebu Pacific flight for US$140 KIX-MNL. In a few days I am flying Cebu again CRK-BKK for US$65, then after 30 days I am doing a quick BKK-KUL visa run for a week then KUL-BKK, cost me US$105 return. I was looking at Air Asia to get to India next as pretty cheap, but might go back to OZ for the Aussie Rules grand final if my team gets in, then start a OWE from NZ or elsewhere (that is why I am on here at the moment, looking for cheap OWE again).
So yeah, that is my opinion, do your Asian travel seperately like I am, then use your Asian flights for something long like DEL-NRT.
Any questions let me know.
