Is the DTV visa enough for a one-way flight to Thailand, or do I need proof of onward travel?

Single is fine

Get a ticket for KL set for 3 months. Cost is negligible and you just planned a vacation for yourself 3 months from now lol

Ask the airline. They make the decision.

If they ask, I just tell them I’m tracing onward by land

Thank You for your helpful report 👍

Congratulations 👏👏👏

PRINT OUT THE EMAIL THAT HAS YOUR DTV VISA.

That's what you should do... print it out.

You may have to show PROOF of your DTV Visa to airline staff on check-in for your flight ✈️ to Thailand...even to the connecting airline staff. Or to the land border crossing entry Thai Immigration Officer.

Upon arrival into Thailand, show the DTV visa to the Thai Immigration Officer and look at the STAMP placed in your passport to be sure you are STAMPED in for 180 days.

Onward flight only required on visa of arrivals

congratulations! i’ll be there by the years end.

The DTV does not require an onward flight.

one way is fine, just show your DTV at check in, if they question your one way.
