>if he picks-up luggage that is not his, what happened to his own, actual luggage?
He doesn't check luggage.
> crazy luggage thievery fetish doesn't fly. is there a regular trafficking of contraband via checked luggage?
He has a fetish for wearing women's underwear and gets off on STEALING it and wearing it. Just like the old school "panty thieves".
It's a symptom he's a likely sexual criminal. This behavior typically escalates.
