Is there a specific reason why you dodged answering to the obvious choice of Singapore Airlines that QRC3288 already mentioned?
Also I'm not quite sure if I understood: You obtained MPC GO with your SIN-TYO flights while you do not credit any of your CX US-HK flights to MPC? Would'nt you already quite easily make DM with 6-8 return US-HK trips in J/F?
Ah, since I suck at multiple quotes, I just addressed, or so I had thought, QRC's and Kaka's posts in a single unquoted one. While the SQ recommendation is certainly not without merit, I dismissed it for a couple of reasons: (1) several less than stellar experiences dealing with SQ (which I feel no need to rehash here); and, (2) have no interest in earning Star Alliance.
As to the second part of your question, when asking for advice, I'm just more accustomed asking it in a brief, to the point, and without any non relevant details. I assume, most are like me, and find it tiresome reading a long expose on a simple question. But, if you're curious, at the risk of boring you, I'll try to clear up your confusion. Up until several years ago, I hadn't visited HK in a long time, and thought it would be nice to visit, for nostalgic reasons. So, I'd fly there once or twice a year and used AA miles to redeem CX F. Then, after AA devaluation, CX F price when from 70k(?) to 120K, I changed to AS, which has kept CX F at 70K, and with a stopover.
Up until then, given the criteria for DM, or even GO, it's obviously a waste of time to even consider it, especially in CX F/J. Now, about 2 years ago, something changed, and I realized there is a possibility that I may have to make at least quarterly trips to HK & SIN. So, a year ago, when this possibility increased, I reached out to MPC and requested a match, and was kindly offered SL. I had credited a couple of CX J/F TPACs to AS, while crediting the intra Asia routes, HKG/SIN/TYO/PVG (on JL/CA/KA), to MPC/Asiamiles. My flight in Feb is the first CX metal TPAC I will be crediting to MPC/Asiamiles.
The quarterly TPACs, possibly 6 - 8 flights, are all future flights, where it's all but certain I'll be the one tabbed to do the traveling. No one can predict the future, but there's a chance I may be taking these flights for several years. I'm just trying to figure out how to maximize my rebate over the next 12 months, and whether or not DM is worth, say, forgoing the miles I can earn on AS or, now, thanks to Kaka, JL. But, if it's DM, I'd have to credit to MPC immediately to even have a shot at it this year.
So, any insights on whether or not DM is worth it? However, based on some of the insights given here, I've decided against the SIN-HKG-TYO detour.
