Early retirement could help ease some of the turbulent times at American Airlines.
The Transport Workers Union said, so far, 713 workers in Tulsa have signed up for the company's "early out" program.
That number could change until Tuesday night's 11 p.m. deadline to sign up.
Based on the number of volunteers, so far about two thirds of the 1,000 Tulsa workers at risk of losing their jobs might ultimately get to keep them.
American has already warned nearly 3,000 Tulsa workers that their job could be affected by the airline's bankruptcy restructuring plan.
