The last time you booked a flight a flight online, you may have noticed a field for entering a KTN (Known Traveler Number). While this number isn't required, having a KTN offers some benefits. If you're flying more than once a year, having a KTN could make your time in airport security faster and easier.
Most applicants receive approval notification in 3-5 days, though some applications can take up to 60 days. Considering this, applicants are encouraged to renew at least 60 days prior to expiry. TSA will notify members with eligibility results. How much does TSA PreCheck® renewal cost?
If you don't find out about the missing PreCheck designation until you're at the airport, take your boarding pass back to the airline check-in counter and ask them to add your KTN to your itinerary — even if you think it's not worth the trouble at that point.
