Using forged documents, such as phony airline tickets, for any reason—including practical jokes or visa applications—is unethical and may even be against the law. Furthermore, attempting to apply for a visa using forged documentation may result in major repercussions, such as the application being denied, legal issues, and trouble getting back to the country. If you haven't booked your flights yet but need the flight itinerary for visa application criteria, you might want to think about buying a real fake ticket or booking through a dummy ticket provider. In less than 10 minutes, you may get a confirmed fake plane ticket for about INR 800/$10.
