While I would like to fly B6 only to try the DirectTV IFE, I find that investing time and effort in TruBlue would result in the exact same zero-value as flying WN.

No partners whatsoever(not even hotel partners )
No PHX presence.
Expiring points.
No F or J
No Clubs
Limited to continental us and a few domnican and PR routes.

I'll stick to AA,AS, and HP and earn miles that don't expire and can take me outside of the us.
