Four more passengers on the Alaska Airlines flight which lost a door plug mid-air are suing the carrier and Boeing. 

The suit filed in Washington State’s King County superior court alleges the plane manufacturer and airline were both negligent in the lead-up to the incident.  Passengers aboard the flight say the incident resulted in physical pain, intense fear, distress, anxiety and trauma. 

Two of the passengers suing are from California, the other two are from Washington.
