Are there any Military or Senior Citizen discounts for TSA PreCheck®?

Service members of all branches of the armed forces and students at the armed forces’ service academies automatically enjoy TSA PreCheck® benefits, with no need to enroll separately. Their DoD ID number is a 10-digit number on the back of the Common Access Card which serves as their Known Traveler Number (KTN).TSA PreCheck® is not currently offered at discounted membership rates for senior citizens. However, please note that TSA allows travelers 75+ to leave shoes and a light jacket on during screening.
