My wife and (young - 4) daughter will be transiting CDG twice this year, and I wish to determine what sort of MMW device use they may be confronted with. Unlike me, I do not believe these travelers have sufficient awareness of the issue, particularly with kids/mmw and questions thereof.

First transit is inbound from PTY, outbound then to RUN. Return trip is the reverse.

On the inbound side, assuming AF checks their baggage through to RUN (another matter I need to check), what security will they need to clear if they stay in the clean zone? How about on the return?

Is RUN considered non-schengen despite belonging to France, meaning they don't have to go through passport control either way in CDG?

Any info/guidance appreciated.
