There’s a reason you see an FA go sit in the cockpit when a pilot needs to take 5.
And what if the FA tries to shutdown the engines? The FA in the cockpit when one pilot goes to the toilet is adding more risk than it mitigates, imho.
This incident will, undoubtedly, lead to more restrictions, or even a complete ban, on jump seat rides!
