In European countries where One-Stop Security (OSS) has been implemented for a number of years, one of the main drivers is commercial. Eliminating transfer security for passengers from the US makes NRT more desirable than say ICN or TPE. Some airports cannot implement OSS in full due to the layout of arrival and departure gate areas.

OSS is implemented in full between most EU countries (the main exception is the UK) as well as for arrivals from the US, Canada, and Singapore. Countries currently in negotiation with the EU include Hong Kong, Israel and Japan.
