As an aside, some credit card companies (my AMEX Platinum, for example) reimburse for Clear security screening membership, and I highly recommend it. While it seems that a growing number of people have TSA PreCheck, there are far fewer Clear members, probably because of the high cost, about $200/year. The lines are virtually non-existent, and the Clear service members not only get you through the ID process, but whisk you right over to the security screening. A no-brainer if you get reimbursed for it.
