Xinhua reported last week that the China Air Transport Association (CATA) has stopped providing paper flight tickets and hopes to eliminate them in China by the end of this year. In the meantime, airlines will continue using exisiting stocks of paper tickets.
The cost of an electronic ticket is about a tenth of that of a paper air ticket, according to the IATA, which is requiring its 261 member airlines to abandon all paper tickets by the end of 2007. See this English Xinhua story for more.
