Paper With a Price

United Airlines says it will stop issuing paper tickets in the United States by next July.

In the meantime, customers who want paper tickets to fly on United will have to pay an extra $20. The added charge goes into effect Thursday.

United converting entirely to electronic ticketing will save money and give customers less hassle at airports.

United is following several other airlines that already have decided to stop issuing paper tickets. The airline has been offering electronic ticketing since 1994 and a spokeswoman says about 70 percent of its customers use e-tickets now.
