Quick update: When the agent scanned by BP, it made a horrible noise. She then checked me off her list of other pax who won the SSSS lottery. I walked down the jet bridge and then had to go to a screening area with other agents who went through all my bags. Agent said it was random. Thankfully, GE worked for me upon arrival, and I have TSA pre for my flight tomorrow afternoon. I hope this doesn't happen again; it's rather unpleasant.
