It is unethical and possibly illegal to use falsified documents, like fake airline tickets, for any purpose, including practical jokes or visa applications. Additionally, trying to apply for a visa with falsified documents could have serious consequences, including the application being rejected, legal ramifications, and difficulties returning to the country. You might want to consider purchasing a real fake ticket or making a reservation through a dummy ticket company if you haven't booked your flights yet but require the flight schedule for visa application requirements. You may purchase a verified dummy ticket for just INR 800/$10 in less than 10 minutes.
