You can, right?! My wife’s in the process of enrolling into Precheck and the TSA said that you cannot use Precheck using a nonrev ticket. I don’t think that’s right because when creating a nonrev listing (specifically talking about my airline), there’s a spot to enter a known traveler ID, which is exactly what the TSA gives you when enrolled in Precheck. You can also use it if you have Global Entry. I’m guessing the TSA doesn’t know every airline’s policy with that, so their blanket statement is that you can’t use Precheck. ??
