As mentioned above, the status match thread is probably the best place to look for info. If you travel mostly transpacific ex-YVR and don't wan't to go through the US all the time, OW is probably your best bet. Unfortunately I don't think either CX or BA will match status. AA will match you, but they will probably make you do a 'challenge' which will mean flying a certain number of miles on AA metal in a given timeframe.

Or as other posters have suggested, you could also stay within *A and simply avoid AC, e.g. by using the SQ YVR-ICN flight. The SQ PPS can be combined with earning miles in another FFP such as BD or UA. However, you might find it difficult to get a match within *A. Maybe you could get some other alliance to match your SE status, and then use that status as a basis for a status match with BD ? (I am not joking, BD are happy to give a Gold status match to anyone, with a Silver companion card thrown in for anyone's dog. Unfortunately they will probably soon be swallowed by Lufthansa.) Or you could simply cut your losses and work your way up from zero in another *A FFP before your *Gold status from AC runs out.

Apologists ? Go to any other airline forum on FT : when somebody with a single-digit post count (though usually identifying themselves a high-ranking elite on airline X) makes their debut with a distraught account of their grievances with airline X, how they never intend to fly airline X again, &c, &c, there is usually, er, some degree of scepticism in at least some of the responses. I don't think it's necessarily attributable to 'apologetics'. Not saying the OP here isn't perfectly legit and justified, but if you are going to introduce yourself to a pseudonymous online forum by throwing down the gauntlet, so to speak, you should at least be aware of how it will look to many of the regulars. Dismissing somebody like acysb with 'obviously doesn't travel much on AC' is putting one's foot in it rather.
