International liquidity

This page from the U.S. Transportation Security Administration lists those countries with 3-1-1 carry-on liquid rules for air travel. The list is long and growing. The Washington Post travel blog reports that Hong Kong has joined the list. Banning liquids is less common in Asia - only Japan and South Korea did so previously. The entire EU is on board with the liquid ban.
