There are continued fears in French Polynesia that Air France could end its Paris to Tahiti service as discussions about pay cuts have been unsuccessful.
A union delegation has visited Paris but failed to meet the CEO of Air France, which for years has been making losses on the route.
Instead it had talks with other top managers who reportedly warned of unspecified unilateral measures if the 116 staff based in Tahiti fail to agree to changes aimed at increasing their productivity by 39 percent.
According to the Nouvelles de Tahiti, the unions were told that their proposal amounting to a 20-percent cut is inadequate.
They say no timeline was given for any possible decision.
The loss of the Air France service would be a blow to the struggling tourism industry which heavily relies on US visitors.
The only other airline linking French Polynesia with Los Angeles and Paris is Air Tahiti Nui.
