Airlines are seeking to undo Biden administration rules that required enhanced training for workers and protection for disabled passengers’ wheelchairs and assistive devices.

The DOT's Biden-era rule protecting travelers with mobility devices is being brought to court by major U.S. airlines.

American Airlines, Delta, JetBlue, Southwest, and United—have joined an airline trade association lawsuit to overturn a Department of Transportation rule that forces airlines to treat wheelchair users and their mobility devices with dignity.
