I participate in a few other airlines' programs with rewards network. It appears this one for TrueBlue isn't yet officially launched. I'm going to hold off on signing up, mainly because usually the programs offer some kind of new member signup bonus and I suspect that once this one is officially announced, it will do the same.
Also, I suspect it will possibly mirror Southwest's Rapid Rewards earning schedule, with periodic bonus thresholds rather than the accrued vip level of other airlines' programs like Delta and American. Perhaps they'd even be incorporated with the TrueBlue Badges program.
