Airline Deregulation Act

If you missed the Supreme Court's decision in Northwest v. Ginsberg it is understandable.  The case had been much overshadowed by the Court's decision the same day in the campaign finance case discussed here in this blog.  

In Northwest v. Ginsberg the Supreme Court held unanimously that an implied covenant of good faith and fair dealing claim related to Northwest terminating membership in its frequent flyer miles program was preempted by the Airline Deregulation Act (ADA) because the implied covenant claim was based on a state-imposed obligation.
