A Connecticut couple is suing US Airways and an affiliate for allowing a California man now charged with kidnapping to fly their 14-year-old daughter to Sacramento last year.

The Hamden, Connecticut, couple is accusing Arizona-based US Airways and affiliate Piedmont Airlines of negligence and infliction of emotional distress. The lawsuit was moved to federal court in Bridgeport last week after initially filed in state court.

Authorities say 29-year-old Nathan Salas of Merced, California, met the girl online and flew her on a US Airways flight from New Haven to Sacramento International Airport, where he was arrested. The girl was unharmed. Salas is detained on $250,000 bail in Connecticut on kidnapping and other charges. His attorney declined to comment.

A US Airways spokesman says the airline doesn't comment on pending litigation.
