The problem is, I already belong to too many programs and have too many member ID numbers to keep track of. If contact information for me changes, a True Blue account would be one more account that I would have to update. So, obviously I would join True Blue if I thought there was something in it for me (other than free flights with points, which given the 1 year expiration of the points, and the fact that SLC is currently served only with two red-eyes, is not too likely to be a factor). SkaterJasp has indicated that there is other considerations (i.e., the account as a bank for flight credits) so I probably will join.
