Technically, you are free to move as much money as you want through the airport. If traveling outside the country, Customs requires you to declare anything over 10k, but that does NOT mean taking or bringing cash or equivalents over 10k is illegal, contrary to some of the ridiculous comments posted by screeners in this forum. You just need to file a form (on the way out), or check your customs declaration on the way in.
