Which is true regarding a passenger traveling with an electronic ticket?

The correct answer highlights that a passenger's ticket is linked digitally without the need for physical copies. An electronic ticket (often referred to as an e-ticket) is stored in the airline's system and is associated with the passenger's personal information and travel itinerary. This digital system allows for a more streamlined check-in process, where passengers can confirm their booking, either online or at the airport, without the necessity for a printed ticket.

Electronic tickets also facilitate easier management of travel itineraries, allowing passengers to make changes or check-in online, further enhancing the convenience of modern air travel. The reliance on digital records minimizes the environmental impact associated with paper tickets and reduces the risk of losing physical copies.

In contrast, the other answers do not accurately reflect the benefits and current practices regarding electronic tickets. For instance, requesting a paper ticket at check-in is not necessary as the e-ticket is sufficient for travel. Additionally, passengers typically do have the ability to make changes to their electronic tickets, depending on the airline's policies. Lastly, while verifying boarding passes is an aspect of the boarding process, it does not necessitate physical copies, as electronic boarding passes can often be scanned directly from a mobile device.
