19 Genius Travel Secrets From Frequent Flyers

I doubt you'll meet a truly frequent flyer who doesn't have TSA Precheck. The program makes airport security a relative breeze. At more than 150 airports, you can access shorter lines and keep your shoes on. Many travel-oriented credit cards will cover the $85 sign-up fee.

Chris Guillebeau, who has traveled to every country on earth, is all about the Chase Sapphire Reserve, which provides a credit for TSA Precheck in addition to other perks. "That one card will get you enough points for two round-trip tickets, and you're not locked into a single airline. You'll also get free primary car rental insurance, and no foreign transaction fees."
