United sued by passenger over alleged seat removal

United Airlines has another passenger complaint to deal with - this time in court.

Karen Shiboleth claims she was forced out of her business-class seat during a flight to London from Newark, N.J., in September and escorted to the rear of the plane without an explanation.

She sued the airline Monday, claiming she's out $9,146 in fees and award points but seeks at least $150,000 in punitive damages 'to deter such behavior in the future.”

United is dealing with a public-relations crisis after a passenger on another flight suffered a broken nose and two lost teeth when he was forcibly removed to make room for the airline's employees. A lawyer for the passenger, David Dao, has said he expects to sue the airline.

Shiboleth says she was on her way to London to begin a master's degree program in international relations at Kings College when the incident occurred. She had originally paid $1,498.90 for a window seat in the economy cabin before using 60,000 American Express miles, and an additional $498.56 in fees and expenses to upgrade to premium economy

She says she further upgraded her seat at the airport, paying $1,149 for a business-class seat in order to 'ease the burden” of her move and accommodate her heavy luggage, according to the suit. About 20 minutes after she boarded the plane, and 10 minutes before takeoff, a gate attendant got on and demanded she move to the back of the plane.

Shiboleth said the attendant grabbed her arm and escorted her, 'in tears,” to a middle seat in the 21st row near the back of the plane, at one point calling her a vulgar name in front of other passengers, according to the suit. The attendant refused to reimburse her for the upgrade and instead offered her a $750 voucher toward a future purchase.

United didn't immediately respond to requests for comment.
