Sources? It’s called present reality. Currently, if you’re put on the actual no-fly list, there’s very little recourse to getting off of it, even if it’s due to an error. It will be no short task to be removed from the list. So no, I don’t think the addition of no-fly list for unruly passengers is a good idea.
As if the government’s no fly list wasn’t enough of an overreach, this would make the situation even worse. Just another “list” that likely to be abused.
I guess that depends on how you define “pick up”. Flying is certainly picking up and has been for a while now, it’s just not anywhere near what it was before the wuflu.
