TSA Pre✓™ fee is non-refundable $85.00. Process takes about three weeks from interview. It is available only to US citizens, US Nationals or US Legal Permanent Residents. Successful applicants receive a Known Traveler Number (KTN) which they include in reservations. Their boarding passes are endorsed 'TSA Pre✓' and they are excused from taking off shoes, taking out laptops and/or liquids. Lines are shorter and quicker. For security, a registered Known Traveler may occasionally not have their BP endorsed and must use normal security lines.

N.B. Only 10 airlines participate in the program.
