But as Grant Martin pointed out in Forbes, this opinion doesn't take into account the extensive background checks required of all the TSA pre-screening programs.
Our takeaway: Americans taking polls about airport security are cranky.
Why wouldn't I just get Global Entry if it includes TSA PreCheck?
Actually, you should just get Global Entry. Even the TSA thinks so.
"Global Entry is a better deal, hands down. We tell people that", Feinstein told Thrillist. "It's a great deal. But only 30 percent of Americans have passports".
Seriously, that's a really sad statistic.
But it's also an essential difference: If you don't have a passport, you can still get TSA PreCheck. You'll need a passport for Global Entry, however, and it costs $15 more. But that's spread out over five years.
Who shouldn't get TSA PreCheck?
People with artificial joints and metal plates in their bodies may not want PreCheck, as they'll prefer advanced imaging screenings over use of a metal detector. Also, if you don't like saving time, then TSA PreCheck isn't for you.
