High court limits suits over frequent flier miles

The Supreme Court has said a Minnesota rabbi who complained about an airline's frequent flier program is out of luck.

The justices on Wednesday unanimously sided with Northwest Airlines and dismissed a lawsuit from Rabbi S. Binyomin Ginsberg that alleged he was stripped of his top-level frequent flier status because he complained too much.

Ginsberg said Northwest, since absorbed by Delta Air Lines Inc., did not act in good faith when it cut him off. But the justices ruled that the federal deregulation of the airline industry in 1978 prohibits most lawsuits like the one filed by Ginsberg.
