I don't know of any "bennies" TSA officers receive from the airlines. The only bennies we receive are those that are consistent with what other airport employees receive...and even that is limited. For example, if airport employees receive a 10% discount buying a cup of coffee at the coffee shop, then TSA employees can receive the same benefit. However, if the airlines offer a special discount to airport employees on air fares, TSA employees are specifically prohibited from accepting those because of conflict-of-interest restrictions.
Privacy Act and FOIA aside, it's nice to know the TSA complies with government ethics rules -- at least at the worker bee level. Sounds like you guys have your ethics act together.
