On December 3, 2013, the Supreme Court heard oral argument in Northwest, Inc. v. Ginsberg. The question here is whether the Airline Deregulation Act of 1978 (the “ADA”) preempts Ginsburg's claim that Northwest Air Lines breached an implied covenant of good faith and fair dealing when it unilaterally terminated his membership in Northwest's frequent-flier program. -- To discuss the case, we have Lee Strang, who is a Professor of Law at the University of Toledo College of Law.
