Thanks so much for ALL your great information!! I did in fact go with NWA as my primary carrier, but will be keeping my stand alone accounts with Alaska and Air Canada as well. I've also gone with Marriott as my primary, with SPG as my back up (was already with SPG) because many of my clients are in areas that don't have anyone in the SPG family in which to stay.

I welcome any and all additional advice.

Thank you again!!
