As someone that also needs to quit smoking, the new policy seems fine to me. I have often wondered how they get the smell out of the cabins.
I will be shocked the day when SC actually passes a law to prohibit smoking. They seem to be one of the last holdouts & I won't even bother stopping overnight or eating in the state when traveling because of it.
They don't do much except when someone complains & then use some sort of a ionizer which supposedly gets the smell out.
