What is an e-ticket, and will I get one?

[StudentUniverse]

An e-ticket is an electronic travel record generated at the time you purchase a ticket which allows you to check in and board your flight without a paper coupon. E-ticketing is an easy, hassle-free way to travel.
Whether you receive an e-ticket or a paper ticket is up to the airline. All domestic flights are e-ticketed and most international flights are as well. Intra-European flights, however, require a paper ticket.

Those who receive an e-ticket will get an e-mail with a link to their itinerary, once their reservation has been ticketed. You should expect this e-mail within 3 days of purchasing online. Once you receive it, simply click on the enclosed link to display your itinerary. To check in at the airport, simply bring a printed copy of your itinerary, along your government issued photo identification card.

In general, most passengers fly on an e-ticket.
