I had a TSO at an airport, LIT I believe but it was during a MR so it could be any one of 8 airports and my memory is fuzzy, specifically tell me that all liquids had to be 3.4 ounces or less so at least one TSO knows the correct number. I, due to all the 3-1-1 stuff, thought that 3.0 was the limit before talking to that TSO and reading this thread, so I can relate to everyone else who is also confused.
