TLDR : Answer Summary
You can fill out the DTAC form anytime within 72 hours before your arrival in Thailand, including while in the plane, during boarding, or right after landing.
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.

Correct, from 72 hours before arrival it is possible. And since you also have to enter the flight number, it is understandable.

If you can count back from zero ( time you land) to 72 that's your answer.

Fill it in any time within the 72 hours of arriving in front of immigration. Just count back. You can even do it waiting to board, when on the plane, or on landing. Up to you.
