I'm curious about the comment about "entitled to an alternative flight". That has not been our experience at all [...] So don't count on much help from NW on a flight time change. </font>
Unfortunately in the case of FF tickets many rules do not apply. That being said, if you are unhappy NW with the alternatives offered in cases of schedule changes [in this case sadly none at all], you can receive a refund -- something NW has indeed offered you in this case.
A bit much to conclude NW won't help based on a single case however.
