The "smart" airlines will not follow NW. Often there are net fares between a pair of cities from more than one airline. Continuing to give miles gives the one giving miles the edge. These low fares are to fill empty seats - most people taking them are not in an emergency situation - it's"there's a cheap fare to...Let's go" I think most people wouldn't be flying unless the fare were cheap and there were miles for those of us who care. Should we be writing to our chosen airline telling them NOT to follow NW?
