American Airlines asked the U.S. District Court in Massachusetts to reverse a jury verdict that awarded nine Boston skycaps about $325,000 in a case involving the state’s tips laws and banned tipping of its skycaps at Logan Airport.

The plaintiffs’ lawyer, meanwhile, has asked the court for treble damages and plans to file an injunction asking the judge to bar American from banning tips because such actions are a retaliation against the skycaps. DiFiore v. American Airlines Inc., No. 1:07-cv-10070 (D. Mass.) On April 28, American Airlines filed a motion for judgment as a matter of law asking the judge to reverse the verdict partially based on the fact that eight of the skycaps technically work for an American Airlines vendor, not for the company. American Airlines also filed a separate motion asking for a new trial or lower damages.
