Airlines are frequently sued for the acts of drunken passengers, typically by flight attendants or other passengers who suffered harm from an unruly traveler during a flight. But this time a husband and wife are suing United Airlines for “negligently” overserving alcohol during a flight from Osaka, Japan, to San Francisco, saying the carrier’s drinks fueled domestic violence between them.
