Appearing in court in northeast Paris, two others who faced the same charges of "organised violence" were acquitted.
Images of furious activists chasing down the executives at the airline's headquarters on the edge of Paris made headlines around the world when the confrontation took place.
The protests were led by the hard-left CGT, France's largest union, over the airline's plans to cut 2,900 jobs.
Ten other former and current employees from the company were fined 500 euros ($530) on Wednesday for damaging the company's property after they broke down a gate at the headquarters during the demonstration.
Pierre Plissonnier, director of long-haul operations at the airline, had told the court of his "humiliation" at seeing pictures of himself scrambling over a fence to escape the mob.
The court also viewed footage of the incident in which a worker can be heard threatening human resources boss Xavier Broseta before he has his shirt ripped off in front of television cameras.
French Prime Minister Manuel Valls had called for the defendants, whom he branded "rogues", to be given stiff sentences.
