Well then it depends from where to where do you plan on traveling?
Domestic - coach. Within that, I would think it shouldn't matter.
What I understand is that ANA uses fewer points, is only round trip ( workaround available), and takes longer for the MR transfer to happen. I don't recall their cancellation policies.
Both won't have have fuel surcharges.
Thanks! Again, though, since it's domestic, there won't be YQ anyway just the $5.60 fees. Although, ilherman just pointed out, it'll be the same 12.5K as UA...
Domestic US economy will be 12.5k Aeroplan miles with no close in fee for a OW.
The beauty of SQ and LH is when redeeming for J.
So same as UA. (No issue of close in fees here.)
Gotcha about the J. Thank you!
