Luddite travelers may need to start making geek friends because the paper airline ticket will be all but extinct by the end of May.

Replacing paper tickets, and the elaborate global system that processed them, with electronic ticketing will save airlines $3 billion annually on the roughly 400 million tickets sold outside of the United States alone, according to the New York Times.

Apparently, 96.86 percent of tickets sold in the United States, Puerto Rico and the United States Virgin Islands last month were electronic, so it does appear that most people are able and willing to travel the digital way. Do you use electronic or paper tickets when you travel?
