Best *A miles program to access OZ, NH F/C?
Now that United has gutted its program, and US has left *A, what's the next best way to access long-haul premium cabins (especially F) on OZ and NH?
I know NH you can do via credit card transfers to their own program, though not sure if that's the best bet to do long-haul flights given distance awards.
OZ, doesn't seem to be a transfer partner for anyone except SPG and not sure if their own miles are best for redemption.
Is it Aeroplan? LifeMiles? TK Miles & Smiles? Or some other miles? Just need a nudge to know where to spend time researching. Thanks!
