Matt Dillon -- Aids in Airport Medical Emergency
Matt Dillon sprung into action at LAX yesterday -- when a woman waiting in line in front of him suddenly collapsed and slammed her head on the terminal floor.
Dillon helped the woman over to a nearby seat ... and stayed with her while airport staff got her water and called paramedics.
An L.A. Fire Department medical response team rushed to the scene and wheeled the woman into a waiting ambulance.
So far, no word on the woman's condition.
