Don't forget Alaska! If you live in California, you may want to join Alaska's program, as it is reciprocal with CO and NW, and works most closely with Northwest. They offer substantial bonus miles on enrollment, that may prove better than the enrollment in NW or CO.</font>
Flying CO will earn miles on AS but they won't be status miles. AS is also partnered with AA, and flying AA will earn AS status miles (as well as NW).
