Air Marshals Do Not Stick-Out Like Sore Thumbs:

10. Memo: "wear coats 'n ties with shined-shoes as anybody else
vacationing in the Bahamas would do."
9. You're packing heat, and thus enter over there at the side, Sir,
where air cops are supposed to. .
8. "This seat here in the front is often for an undercover guard & no
smoking is allowed, Mam"
7. "Your gazillion points aren't worth anything--so why worry, Mr.
Agent--few promotional seats are available anyhow on customarily
crowded flights even as if those fake points really mattered."
6.--1. Be paranoid and hava nice flight.
