Yes, active duty military members get TSA PreCheck for free. The benefit covers every branch — Army, Navy, Air Force, Marine Corps, Space Force, and Coast Guard — along with Reservists and National Guard members, and it extends to DoD civilian employees, service academy cadets and midshipmen, and officers of the U.S. Public Health Service and NOAA Commissioned Corps.1Transportation Security Administration. Free TSA PreCheck for Uniformed Service Members and DOD Civilians Civilians pay between $77 and $85 to enroll; service members pay nothing because their existing security clearance already satisfies TSA’s vetting.3Defense Travel Management Office. Commercial Air – TSA PreCheck
There is no application to fill out and no appointment to schedule. The benefit is essentially waiting for you to switch on the first time you book a flight.
How to Turn the Benefit On
Your Known Traveler Number is the 10-digit DoD ID number printed on your Common Access Card. Enter it in the Known Traveler Number field when you book a flight, whether the trip is official or personal.2Transportation Security Administration. How Do I Get TSA PreCheck as a Member of the US Armed Forces That number links your reservation to TSA’s system and triggers the PreCheck designation on your boarding pass.
Most major airlines let you save the number in your frequent flyer profile, so it gets applied automatically to every future booking. If you travel on orders, add the number to your Defense Travel System profile so it carries over to government-booked itineraries.4Defense Travel Management Office. Commercial Air – TSA PreCheck
One thing that surprises people: showing your CAC at the checkpoint will not get you into the PreCheck lane. TSA is explicit about that. The PreCheck indicator has to appear on your boarding pass, and the only way to put it there is to enter your DoD ID number in the Known Traveler Number field before or during check-in.5Transportation Security Administration. TSA Cares – Military and Veterans
Name Mismatches Are the Usual Problem
The system checks your reservation against the Defense Enrollment Eligibility Reporting System (DEERS). If the name on your ticket doesn’t match DEERS exactly, the indicator won’t appear. Suffixes like “Jr.” and “III,” middle names, and hyphenated last names cause most of the trouble. Before booking, make sure the name on your CAC matches what you enter on the reservation, character for character.
If you find a discrepancy, fix the underlying DEERS record. Call the Defense Manpower Data Center support office at 800-538-9552 (Monday through Friday, 8:00 a.m. to 8:00 p.m. ET, closed on federal holidays) to find out what documents you need.6Veterans Affairs. How Do I Change My Name in My DEERS Record Do it soon. Until the record is corrected, the mismatch will block PreCheck on every flight you book.
Checking Your Boarding Pass
After your ticket is issued, look for a TSA PreCheck indicator. Airlines print it in different formats: “TSAPRECHK,” “TSA PRE,” or the TSA PreCheck logo. If it isn’t there, ask the airline to update the reservation at the check-in counter. A missing indicator almost always means the DoD ID number wasn’t entered correctly or the name didn’t match DEERS.
In the PreCheck lane, you keep your shoes, belt, and light jacket on. Laptops and travel-sized liquids stay in your bag.7Transportation Security Administration. TSA PreCheck for Uniformed Service Members Random additional screening can still happen occasionally, but it’s the exception.
Traveling With Family
Your free PreCheck doesn’t extend to your whole family, but children get some leeway.8Transportation Security Administration. TSA PreCheck for Families
- Children 12 and under can walk through the PreCheck lane with you regardless of what their boarding pass says. They don’t need a KTN of their own.
- Children ages 13 to 17 can use the PreCheck lane only when the indicator appears on their own boarding pass. That requires the child to be on the same reservation as the eligible parent, with the parent’s boarding pass showing the indicator. Leave the KTN field blank for the child if they don’t have their own; entering yours will not work.9Transportation Security Administration.

Spouses
Spouses do not get free PreCheck through the service member’s status. They apply on their own, go through a background check, and pay an enrollment fee. Military spouses do receive a $25 discount on enrollment or renewal, and they qualify by presenting an unexpired DoD or Uniformed Services photo ID card that lists the relationship as “Spouse.”10Transportation Security Administration. Military Spouse TSA PreCheck Enrollment Discount The discount process varies by enrollment provider; with IDEMIA and CLEAR, you typically pay the full fee upfront and then email a copy of the spouse ID to receive a rebate.
Survivor Families
Families of service members who died on active duty, or from a service-connected injury or illness after separation, can enroll for free. Eligible family members include the fallen service member’s spouse, parents, children, and siblings. Enrollment requires a verification letter from the Tragedy Assistance Program for Survivors (TAPS) or a TSA acknowledgment form. Request one by contacting TAPS at 800-959-8277 or TSA at 866-289-9673.11Transportation Security Administration. Military Survivor Family TSA PreCheck Enrollment
What Happens When You Separate or Retire
The free benefit ends when you leave the service. Military retirees and veterans don’t keep it.5Transportation Security Administration. TSA Cares – Military and Veterans Your military KTN stops working after you separate from DoD, and TSA’s guidance doesn’t mention any grace period. If you want to keep flying with PreCheck, enroll as a civilian before your separation date so you have a new KTN ready to go. Civilian enrollment runs $77 to $85 depending on the provider, and many travel credit cards reimburse the fee.12Transportation Security Administration. TSA PreCheck
Adult dependents (spouses and children 18 and older) and DoD contractors are also not covered by the free program. Each has to enroll through the standard civilian process.1Transportation Security Administration. Free TSA PreCheck for Uniformed Service Members and DOD Civilians
PreCheck Only Covers Domestic Screening
Free military PreCheck applies to TSA screening at U.S. airports. It works on any flight departing from the United States, including international departures, because you still pass through TSA before boarding. It does not speed up customs when you return from overseas.
Global Entry is the Customs and Border Protection program for that, and it includes TSA PreCheck as a built-in benefit. Global Entry is not free for military members. It has its own application and in-person interview, and it costs $120. If you travel internationally often, it may be worth the investment because it covers both programs at once, and many premium travel credit cards reimburse the fee. If you mostly fly domestically, the free PreCheck benefit already handles what you need.
