SAN FRANCISCO — It's been a rough few years for airline customers in the United States.

Snack options are on the decline, baggage fees are on the rise, and the likelihood of being forcibly removed from a plane against your will seems to be at an all-time high.

Take this as something of a consolation for weary, under-appreciated passengers: The U.S. Court of Appeals for the Ninth Circuit on Wednesday revived a seven-year-old class action lawsuit against US Airways Inc., which seeks refunds of baggage charges paid by passengers whose bags were delayed or lost. The Ninth Circuit decision, a win for name plaintiff Hayley Hickcox-Huffman and her lawyers at Foley Bezek Behle & Curtis, reverses a ruling that held the passengers' state-law contract claims were pre-empted by the Airline Deregulation Act, which prohibits states from regulating airlines prices, routes, or services.
