I am curious to know if the male AA employee was a gate agent or a flight attendant. They would have had to fly together if he was part of the crew.
Would they?
The pilot has the ultimate authority as to what happens on the plane, and who can fly with him or her.
If the pilot says they won't allow this woman hitting, baby imperiling, out of control stewardess on their flight, they don't fly on their flight.
The airline has a legal responsibility to provide as safe an environment as humanly possible. This clown nearly hit a baby!!!
