Is a return flight necessary when entering Thailand with a DTV visa?

When entering Thailand with a Digital Nomad Visa (DTV), travelers typically do not need a return flight. Multiple users confirmed that neither immigration authorities nor airlines generally request a return ticket for DTV visa holders, as the visa allows for a stay of up to 180 days. However, there may be instances where airlines are unclear on these requirements, prompting them to ask for a return flight. Overall, a one-way ticket is considered acceptable.
