International Harmonization Of Security Measures

Read about our International Harmonization security measures.

On November 6, 2006, the members of the European Union, as well as Norway, Switzerland, and Iceland, implemented new security rules pertaining to liquids in carry-on bags in an effort to harmonize, to the maximum extent possible, with measures enacted by the United States and Canada in September 2006.

These changes were the first in Europe since the total ban enacted after the United Kingdom foiled a liquid explosives plot on August 10, 2006.

Effective November 6, 2006, travelers going to and from the U.S., Canada, the 25 member countries of the European Union, as well as Switzerland, Norway and Iceland, can use the same one quart, clear plastic, zip-top bag to transport their travel-sized liquid, gel and aerosol items in carry-on bags through various security checkpoints here and abroad. To put this in perspective, approximately half of the world's travelers are governed by similar security measures. This is an historic and unprecedented accomplishment.

This collaboration is a monumental development in international airline security. The clarity and consistency of these security measures help to remove confusion for passengers traveling internationally while making the detection of threat items easier at the checkpoint for all security officers.
