It is unethical and sometimes illegal to use false documents, such as fake plane tickets, for any purpose, including practical jokes or visa applications. Additionally, trying to apply for a visa using falsified documents could have serious consequences, including the application being rejected, legal problems, and difficulties returning to the country. You might want to consider purchasing a genuine fake ticket or making a reservation through a dummy ticket provider if you haven't booked your tickets yet but require the flight schedule for visa application requirements. You may purchase a verified fake plane ticket for roughly INR 350 or $5 in less than 10 minutes.
