If your KTN is still active, confirm with your airline that your KTN, name, and date of birth are accurate.

You can also confirm your airline participates in the TSA PreCheck® program, by clicking here. If you are unclear why you are not receiving the TSA PreCheck® indicator on your boarding pass, first check that your membership has not expired by looking up your KTN (Known Traveler Number) here. TSA PreCheck® enrollees found to have committed a disqualifying offense may have their TSA PreCheck® enrollment temporarily suspended or permanently disqualified, depending on the severity of the offense.

Resolution typically takes less than 30 days, but can take up to 90 days. Temporary suspensions may occur as a result of recurrent vetting. TSA PreCheck® enrollees undergo recurrent criminal history vetting as a condition of their TSA PreCheck® enrollment. The duration of disqualification from participation in TSA PreCheck® is related to the seriousness of the violation and/or a repeated history of regulatory violations. Membership suspension can last up to five years for a first time offense or be permanent for egregious incidents or repeat offenses. If you commit certain violations of federal security regulations, such as assault, threat, intimidation, or interference with flight crew, physical or sexual assault or threat of physical or sexual assault of any individual on an aircraft, interference with security operations, access control violations, providing false or fraudulent documents, making a bomb threat, or bringing a firearm, explosive, or other prohibited item to an airport or onboard an aircraft, you are denied expedited screening for a period of time. Please separate medications and inform the TSA officer that you carry these items for your service dog. Medication for service animals must go through X-ray or inspection screening. You may request to move to the front of the line upon your return. If you need to relieve your service dog and must exit the security checkpoint, you and the service dog will need to go through the screening process again. Items that are necessary to maintain control of the service dog/animal or indicate that the service dog/animal is on duty do not require removal to be screened. Service dog/animal collars, harnesses, leashes, backpacks, vests and other items are subject to security screening. If you have concerns about your screening, you can ask to speak with a supervisor or passenger support specialist at any point during the process.

TSA will not separate you from your service animal. If the metal detector alarms, you and your service dog/animal will undergo additional screening, including a pat-down.ĭuring the additional screening, do not make contact with the dog/animal (other than holding the leash) until a TSA officer has completed inspection of your dog/animal. If you opt not to be screened by the Advanced Imaging Technology (AIT), or a walk-through metal detector (WTMD), you will undergo a pat-down. You may walk through together or you may lead the animal through separately on a leash. You and your service dog/animal will be screened by a walk-through metal detector.
