I've done around 18 flights since January of 2021, almost all of them was Precheck. I even got Precheck in a rapid pace with KTN within 3 business days or so? My last 3 flights in the past week though I've gotten the random beep at 3 different airports (EWR, JFK, BNA). Talk about unlucky? I'd say I'm on some sort of list but the metal detector doesn't know me going through CLEAR to me walking through it.

All 3 have been bomb swipes, Two on my phone and one on my hands. I have another 2 flights this weekend, let's see If I keep my unlucky streak. If it's just a swab and on my way I'm cool, but one of them nearly cost me my flight in waiting for someone to swab my device.
