An electronic ticket or e-ticket is used to represent the purchase of a seat on a passenger plane, usually through a website or by telephone. This form of airline ticket rapidly replaced the old home of multilayer paper tickets (near zero to 100% in 10 years) and became mandatory for IATA members from 1 June 2008. In recent years, when paper tickets were still available, airlines often pay extra for issuing them. E-tickets are available for some entertainment.

Once a reservation, an e-ticket exists only as a digital record in the airline computers. Customers usually print a copy of the receipt that contains the record locator or reservation number and e-ticket number.

To critics, Joel R. Goheen is recognized as the inventor of electronic ticketing in the airline industry, an industry with worldwide sales of electronic ticket (the industry standard) represents over 400 million (U.S.) per year (2007). View patents for electronic ticketing in the airline industry.

Electronic tickets are introduced in road, urban or rail public.
