A selected summary of Southern California-related business litigation developments during the past week.

Travel Agents Sentenced: Their federal terms ranged from nearly two years to four years in prison for running a scheme to defraud American Airlines of frequent-flier tickets totaling $1.3 million between 1986 and 1987. Through a computer reservation terminal at North Ranch Travel Agency in Woodland Hills, the three men changed American Airlines’ records on frequent fliers, crediting fictitious accounts with miles flown by legitimate passengers not enrolled in the frequent-flier program. The defendants then used the miles to apply for free flights, sold them for profit or gave them away to friends and family. They were convicted after a trial last year. (Case No. 90-409. Sentencing Feb. 5).
