Try going through Frankfurt. My airline is X-rayed and physically searched. Alongside us is Royal Air Brunai and Malaysian, who are just waved through. On querying this with our station manager, I was told that unless the airlines country agrees to the search, it is not done.
It doesn't take a genius to work out that a member of these crews could be threatened or bribed to carry something airside and then hand it on to a passenger boarding any flight. There is no further security for passengers before boarding.
I'm glad to see that CDG have tightened up. Until recently, crews were driven to the A/C with no search. You could then wander up the airbridge into the terminal. Once again it only takes one crew member to be frightened into carrying something airside to make a complete nonsense of the millions spent on security by the state and by the airlines.
States should have the gumption to tell these countries - no search - don't bother coming.
