The airline revoked Rabbi Binyomin Ginsberg's membership in the WorldPerks Platinum Elite program in June 2008. He had complained 24 times in eight months about Northwest's service and sought "compensation over and above (Northwest's) guidelines," according to the airline's written argument.
Ginsberg, who flies 75 times a year as a lecturer, filed a federal class-action lawsuit seeking $5 million, saying he was dropped without adequate cause. He acknowledged complaining about getting bumped from flights, but not every time.
"Rabbi Ginsberg appealed solely with respect to the claim for breach of the implied covenant of good faith and fair dealing," Ginsberg's written argument said.
But Northwest, which is now part of Delta Air Lines, argued that the Airline Deregulation Act of 1978 prevents lawsuits governing "price, route or service of an air carrier."
It is true that the Airline Deregulation Act preempts state law claims that "relate to" airline prices, routes, or services.
What will be interesting in this case is whether the Supreme Court determines, as it has in the past, that frequent flyer programs represent contract rights and voluntary airline undertakings that are not preempted under the federal deregulation act, or whether the passenger's particular claim here (including "bumping"), falls within the "price, route, or service" an air carrier offers so as to be preempted.
