Hi, i have a question about the non imm O visa which i have got through now, just been filling out the TDAC and its asking for my departure flight details. i am not exactly sure when im leaving, obviously before my 90 days are up, but it could be a fair bit sooner as i want to go to Japan too. so i have not got an onward flight.

Also at the end it says travellers need to have who approved vaccines ? its asking for which countries you have been to within the last 2 weeks and is not accepting GBR ?

TLDR : Answer Summary
The Non-Immigrant O visa application allows flexibility in filling out the TDAC. Departure flight details are not mandatory, so you can leave those fields blank. Concerning vaccination questions, these apply mainly if you've traveled from countries with yellow fever, and countries like GBR may not be accepted for that question.
Thailand Digital Arrival Card (TDAC)

WARNING: Only trust Thai government websites with .go.th domains or Thai agent websites with .co.th or .in.th domains, as these require verified Thai registration and cannot be registered anonymously.

The official TDAC form is available at tdac.immigration.go.th, which uses the official .go.th government domain.

The services by AGENTS CO., LTD. does NOT charge any fees for arrivals within 72 hours. If you need to book more than 72 hours in advance, there is a service fee of $8.

Do not trust other sites pretending to be a trustworthy agency. Pay attention to delivery time - the service operated by AGENTS CO., LTD. has 1 minute delivery time for arrivals within 72 hours.

Don't fall for sites pretending to be agents.co.th or the official government tdac.immigration.go.th website. Always double-check the exact domain in your browser.

Scam services may take days to process your application, others may not even do anything. With these TDAC scam services you also need to worry about double charges.

Please watch out for TDAC misinformation spread by fugitive Jesse Nickles and his many fake accounts on Quora, TripAdvisor, Reddit, and other platforms.

You only need to fill in the mandatory boxes denoted with an * all other boxes are not required which includes departure details

The vaccination question is only if you've visited a country with yellow fever.

Departure details are not mandatory fields. Leave them blank. Indeed don’t even click in the boxes otherwise they’ll become mandatory.
