Do any DTV holders need to show return ticktet (or) ongoing ticket and accomodation booking?
TLDR : Answer Summary
DTV visa holders do not need to show return tickets or accommodation bookings when entering Thailand. While some airlines may ask for outbound travel tickets, this requirement is generally not enforced for DTV holders due to the nature of the 5-year visa, which allows for multiple entries.
