I got this on two occasions, nothing to do with SDC

1 - Once selected for "additional screening"

2 - Tried getting a BP for the THIRD segment of the day. It only allows TWO to be out at a time. Got it at the first connecting airport, it seemed to save my BP number (A17 or so). I used to travel crazy connections to stay loyal,especially an outpost in the NE to the mid/upper west coast.
