U.S. District Judge Monti Belot has set a hearing in a lawsuit against Boeing.
The Society of Professional Engineering Employees in Aerospace filed the lawsuit in 2005.
The suit over pensions and retiree medical benefits stems from when Boeing sold its commercial aircraft operations in Wichita to Spirit Aerosystems.
The Machinists union joined the lawsuit in January of 2007, and the court later consolidated it into the litigation of a similar case brought by several workers.
The parties are now arguing over what information to exchange during discovery in the case.
Belot has scheduled a status conference in the case for June 23rd.
