In Japan, they too are affected and getting tough now-apparently!

Japanese airlines have warned their passengers that they will be forcibly restrained for unruly behavior following reports that rowdy behavior by passengers more than doubled in 1999.

In addition to violent acts, the 330 reported incidents last year included sexual harassment and drunkenness.

Japan's three biggest carriers - Japan Airlines, All Nippon Airways and Japan Air System - began telling customers in April that they will restrain any passenger who threatens others or refuses to heed orders from crew members.
