The people who fly the commuter airlines that link with TWA are starting informational picketing at Lambert-St.Louis airport. Trans-States Airlines pilots say there won’t be any service disruptions because of their picketing. Trans-States operates Trans-World Express, which provides links to TWA from 40 cities in Missouri and other states. Talks with management since June of ’98 have not produced a new contract. The Air Line Pilots Association says Trans-States’ salaries are 30 percent behind industry averages.
