The head of the International Air Transport Association on Thursday urged Japan to catch up with industry trends by speeding up implementation of e-ticketing and getting rid of its fuel tax on domestic flights.

"We're a bit disappointed with Japan," IATA Director General Giovanni Bisignani told a news conference in Tokyo, referring to its low market penetration of 50 percent in e-ticketing.

He also called for the abolition of Japan's fuel tax imposed on fuel used for domestic flights -- a rare practice.
