I ran into a nasty little situation where I asked a TSO to call his supervisor, and he said I would have to step aside and wait 20-30 minutes because 'they were all in a meeting'. I wish I knew a list of titles of people required to be on call at the airport, so I could be an IKWYRT (I Know Who You Report To).

I would like to assemble a hierarchy, a list of titles and employees, that you can ask to be called to the checkpoint when an issue arises. I know there are also airport and airline security people that can be called, and I would like to merge them into the list at the appropriate levels. I will start the list using my bet guesses, and if people can post additional or corrected info, I will integrate it into this first post, and possibly into the Glossary:

Level 1 - Initial Contact
TDC (Travel Document Checker) Verifies that ID matches boarding pass
TSO (Transportation Security Officer) Basic entry-level screener
? BDO (Behavior Detection Officer) Wanders around and looks for 'suspicious' pax

Level 2 - Supervisors immediately available at each checkpoint
LTSO (Lead Transportation Security Officer, aka "two-stripers") Level 1 Employees will call these more experienced employees over when they are not certain how to do their job.
? STSO (Supervisory Transportation Security Officer, aka "three-stripers", aka "sups") This is the first real level of supervision and authority among TSOs.

Level 3 - People who should be nearby (in the terminal?)
LEO (Law Enforcement Officer) Real officer with arrest powers, not a TSA employee
?GSC = Ground Security Coordinator (airline employee responsible for security in their area)

Level 4 - Airport-Level Authority
BAO = Bomb Appraisal Officer - on-call at the airport to resolve any explosives question

Level 5 ??

Level X - Issues escalated after the event
1. TSA website
...
99. TSA Administrator (John Pistole)
100. DHS Secretary (Janet Napolitano)

I need Help placing or explaining these employees:
TSM = Transportation Security Manager
AFSD-LE = Assistant Federal Security Director for Law Enforcement
AFSD-O = Assistant Federal Security Director for Operations
AFSD-S = Assistant Federal Security Director for Screening
AFSD = Assistant Federal Security Director
DFSD = Deputy Federal Security Director
FSD = Federal Security Director
TSA Ombudsman?
