A real story (i.e., real personal experience from years ago) with little more than the dates (and perhaps individuals names) changed (i.e., even if a decades-old story) would work rather well -- especially if the prior purpose of a trip to the same or a similiar place was more "typical". The nitwit questioning will routinely fail to catch such. And if a terrorist has resolved his/her moral qualms (if any) about killing people, I doubt they'd have any more serious moral qualms about lying.
