Hi. And apologies for this. But I am getting conflicting info on line.

A question on the TDAC form please. I board my flight in Dublin Ireland. I transfer to a new flight in Abu Dhabi ( connecting flight) and arrive in Bangkok

Form needs country from which I boarded ? Is this Dublin Ireland or is it UAE?

Also wants flight number. Is the Dublin to Abu Dhabi or Abu Dhabi to bkk ?

Many thanks for the help

TLDR : Answer Summary
When filling out the TDAC form for your flight to Thailand, you should indicate the country from which you last boarded your flight, which in this case is the UAE. For the flight number, provide the one for your flight from Abu Dhabi to Bangkok, as this is the final leg of your journey entering Thailand. There seems to be a consensus among commenters that the specific details are not closely scrutinized by the Thai authorities.
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.

what you put down is irrelevant, Thailand doesn’t care.

It makes no difference.

They want to know the information on the flight that has you arriving in Thailand.

But in reality, it doesn't matter. The system is completely automated and no one is checking.
