Kathy Kuhn didn't hit the jackpot in Las Vegas. She claims the plane ride from Detroit wasn't a winner, either.
The suburban Detroit woman is suing Northwest Airlines, saying she injured her knee while trying to get settled in a middle seat.
The 58-year-old Kuhn says she wrenched her knee while trying to climb over an armrest that wouldn't go up. Her husband, Gayl, said Monday that she used crutches during their stay in Las Vegas in 2007.
Kuhn had surgery to repair a ligament when they returned home to Eastpointe. Her lawsuit against Northwest was moved last week to federal court in Detroit from state court and seeks an unspecified cash award. In a court filing, Northwest denies liability.
Northwest is a subsidiary of Delta Air Lines Inc.
