You can use a dummy ticket to apply for a visa because it has all the necessary information, such as the date, the trip’s itinerary, the passenger’s contact and personal details, and a current PNR. In the context of airline reservations, itinerary refers to a dummy ticket, a hold ticket for which payment is still waiting, and a dummy ticket with a live PNR that is visible on the airline website. A dummy ticket contains all the information needed to fulfill immigration and visas.
