TLDR : Answer Summary
Your friend can apply for the online application (TDAC) to enter Thailand up to 3 days prior to his arrival, or he can even do it during his travel to the airport or right before checking in. Additionally, he has the option to submit the application as soon as he lands at the airport, before going through immigration.
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 tdac.in.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.

even upon your flight landing on arrival at the airport in Thailand, anyone can submit their TDAC before going into the queue for Thai Immigration Arrivals

Or, if you would like to be more prepared than that, 3 days before your arrival in Thailand

He can do it on his way to the airport. or while standing in line to check in. Or the day before.

It takes 2 minutes and there's no wait time.

it’s not an entry approval form. That’s at the discretion of the immigration officer as usual.
