What are the flight and accommodation requirements for the DTV visa application in Thailand?

When applying for the DTV visa in Ho Chi Minh, travelers often find themselves needing to show proof of a booked flight and accommodation in Thailand. This can feel challenging, especially for those who want to wait until their visa is confirmed before making travel arrangements. While some advice suggests that using a random flight number may suffice, the requirement for proof of accommodation can complicate things further, creating a situation where applying for the visa seems premature without concrete travel plans.
