What's worse than waiting in line? Not much, which is why IdentoGO, the provider of TSA Pre✓® enrollment services, is joining forces with Live Nation to make it easy for concert goers to enroll for TSA Pre✓® . To enroll, present a government issued I.D. with proof of U.S. citizenship (i.e. a passport or birth certificate) and a credit card payment of $85 for a five-year membership (that's only $17 a year!). See a complete list of acceptable identity documents. Once approved, you'll receive a KTN (Known Traveler Number) and you'll be on your way to enjoying not only a faster airport security experience!
