TSA precheck not passing through?
Bought flights from STL to CUN and input my known traveler number. Everything goes through and my boarding pass shows the TSA precheck mark.
Go through precheck line, only to have the TSA agent tell me that I dont have precheck. Ignores my boarding pass and says the airline didnt send it through. I can either go through the normal line or go back upstairs to the ticket counter.
First time flying Frontier and first time this has happened. Anyone else?
