Our flights are not the only ones with mom and pop in the back of the plane. As Attarian admits United had and still has systemic problems. These problems don't get fixed by flying the junk and putting bandaids on the problem. If it is safe, an exception, everyone is comfortable with the plan and it won't screw crews and customers downline then sure.
What is disturbing is how quick some are to question other Captains' motives and authority based on hearsay and management BS.
