If they go boom in the cabin the damage is predictable based on exactly where the attacker decides to set it off, which is nothing to do with boarding pass.
A small boom set by a clever attacker in the right place is going to be as big a threat as a large boom placed randomly, and that's before we get onto stuff like shaped charges and really clever placement.
I strongly suspect this is the issue.
