The people that abide by the rules have an entirely reasonable expectation that the rules will be enforced.
So I expect there to be consequences for non compliance.
You do not have a “right” to fly on what is public transportation. You engage in a contract with a transportation provider. This comes with privileges and obligations on both sides.
You’ve been given 3 chances already, upon purchase, upon checking in and at the gate.
You should not have to be treated like a 4 year old man child once you get on board.
They should remove many more people and prohibit them from flying on brand X for 30/60/90 days and forfeit the ticket.
Sadly it’s largely virtue signaling.
