Can I use our Known Traveler Number for TSA PreCheck if the airline we are flying doesn't recognize them in their system?
2 Answers
No, you cannot. TSA PreCheck requires the participation of the airline. If your airline doesn't participate, you can't use it.

Why can’t I use the TSA Pre✓® lanes when traveling on any airline?
Passengers must be traveling on an airline that has entered into a partnership with TSA. Under this partnership, TSA works with the airline to establish system and checkpoint requirements and determine operation of TSA Pre✓® lanes at airports.
You can find a list of participating airlines at https://www.tsa.gov/precheck/map.
Here are the airlines that participate in TSA Pre-check:
Aeromexico
Air Canada
Alaska Airlines
Allegiant Air
American Airlines
Aruba Airlines
Avianca
Boutique Airlines
Cape Air
Delta Air Lines
Emirates
Etihad Airways
Frontier Airlines
Hawaiian Airlines
JetBlue Airways
Key Lime Air
Lufthansa
Miami Air International
OneJet
Seaborne Airlines
Southern Airways Express
Southwest Airlines
Spirit Airlines
Sun Country Airlines
Sunwing Airlines
United Airlines
Virgin America
Virgin Atlantic
WestJet
Xtra Airways
If your airline is not listed, then you won't be able to enter the TSA Pre-check lane at the airport. An easy way to check, is to look at your boarding pass, and if you see TSA Precheck listed, then you may use the TSA Pre-check lane. If you have a Known Travelers Number (KTN), you can also call your airline to add it to your reservation.
