BOSTON - The First Circuit U.S. Court of Appeals on July 9 upheld the dismissal of two class suits filed by airline skycaps claiming that their employer improperly retained baggage-handling fees for curbside service, finding that the complaints "intrude into a no-fly zone demarcated by the preemption provision of the Airline Deregulation Act (ADA)" (Joseph Brown, et al. v. United Airlines, Inc., No. 12-1543, Ben Mitchell, et al. v. US Airways, Inc., No. 12-2056, 1st Cir.; 2013 U.S. App. LEXIS 13804).
