From USA TODAY's Airport Check-in column:
France has joined other European Union countries in waiving the requirement for air travelers who have already been screened at another European airport to be screened a second time when making flight connections. The so-called One-Stop Security, already allowed in the majority of EU countries, will be rolled out at French airports throughout 2009, says the International Air Transport Association.
IATA estimates that this will affect 6 million passengers and save $30 million a year. "It is a waste of time, effort and resources to ask passengers to stand again at security if they have already been checked by a competent screening authority a few hours earlier," says IATA's CEO Giovanni Bisignani, in a statement. The United Kingdom and Ireland have yet to join the pact.
