We're talking about grown adults here, Who should know how to conduct themselves while traveling. Some don't just rage, But attack flight attendants and threaten the safety of other passengers. The consequences imposed depends on the type of action. Simply screaming or cursing at others? Banned from flying for at least six months. Physically attacking others? A fine, Years long flight ban, And notification of law enforcement authorities. These are just some general ideas, But there needs to be some deterrence. I understand the frustration around mask mandates on flights, (especially long ones) but that does not entitle you to act in any manner you wish.
