What does the term "e-Ticket" signify in American Airlines travel?

The term "e-Ticket" signifies a digital ticket purchased for a flight. This modern ticketing method simplifies the travel experience by eliminating the need for physical paper tickets. When a passenger books a flight with an e-Ticket, the airline records the ticket electronically, allowing travelers to check in online, receive a confirmation via email, and access their flight details quickly. The convenience of an e-Ticket streamlines the boarding process, as travelers can present their identification and check in using their mobile devices or at airport kiosks without needing a physical ticket.

In this context, the other options do not capture the essence of what an e-Ticket is. A mobile boarding pass is a related concept but is not synonymous with an e-Ticket itself, as it is a step that follows the ticket purchase. The ticket upgrade option refers to changes in seating class and does not pertain to the ticketing method. Lastly, a paper ticket represents an older method that has largely been replaced by electronic ticketing systems. Therefore, the correct representation of an e-Ticket is that it is a digital ticket purchased for a flight.
