It should be noted that, in its current incarnation, those that access the lanes via being a frequent traveler are not actually vetted. Personally, I think that Pre should be open only to those that are Global Entry or are otherwise cleared by the TSA. That someone flew 25k miles (or less) without incident does not seem like a particularly rigorous vetting process.
