Four flight attendants on the Alaska Airlines, 737 MAX 9 plane that experienced a mid-air cabin panel blowout in January last year are suing Boeing for physical and emotional injuries.

Footage captured by passengers on the flight showed a gaping hole left by the door as pilots made an emergency landing last year.

United Airlines Holdings Inc. flight attendants rejected a new contract that would have provided cumulative pay increases of as much as 45.6% over five years.
