The AAnytime award on AA is definitely a pretty low value, so I'd try and find something that will work with a standard all-partner award. Regardless of whether you choose CX or JL, you'll have some nice options. there are also lots of connection points in the north america, so make sure to consider them all (SFO, ORD, LAX, YVR, JFK, HNL, YYZ, etc.)
