Northwest Airlines’ mechanics are set to walk off the job on Saturday if labor and management cannot come to an agreement on contract terms. The airline says that it has hired and trained sufficient replacement workers to keep the carrier running should there be a walkout, and the public appears to believe them, as ticket sales have not fallen off. If you’re flying Northwest this weekend, check out the Labor Update portion of Northwest’s website during the day. My guess? They’ll extend the strike deadline and make a deal. Northwest is the only major carrier not to receive significant givebacks from labor.
