Don't need a long credit history to fly as a passenger. People fly every day with no credit (or even derogatory credit) histories. Unless you're advocating a minimum FICO score to be allowed to fly (sorry, you're under 680 - no flight for you). Only thing the credit history does (and will ever do) is serve as a flag for extra screening, and the usefulness of that wasted time requires that you assume that the screening will relieve the bum of a "prohibited item" without which their plot will be unsuccessful. One would hope that our nation's security doesn't rely on such fanciful assumptions.
